Graphical user interface

A graphical user interface, or GUI, is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.

The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term GUI tends not to be applied to other lower-display resolution types of interfaces, such as video games (where head-up displays (HUDs) are preferred), or not including flat screens like volumetric displays because the term is restricted to the scope of 2D display screens able to describe generic information, in the tradition of the computer science research at the Xerox Palo Alto Research Center.

GUI and interaction design

Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human–computer interaction. Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline named usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks.

The visible graphical interface features of an application are sometimes referred to as chrome or GUI. Typically, users interact with information by manipulating visual widgets that allow for interactions appropriate to the kind of data they hold. The widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of users. A model–view–controller allows flexible structures in which the interface is independent of and indirectly linked to application functions, so the GUI can be customized easily. This allows users to select or design a different skin or theme at will, and eases the designer's work to change the interface as user needs evolve. Good GUI design relates to users more, and to system architecture less. Large widgets, such as windows, usually provide a frame or container for the main presentation content such as a web page, email message, or drawing. Smaller ones usually act as a user-input tool.

A GUI may be designed for the requirements of a vertical market as application-specific GUIs. Examples include automated teller machines (ATM), point of sale (POS) touchscreens at restaurants, self-service checkouts used in a retail store, airline self-ticket and check-in, information kiosks in a public space, like a train station or a museum, and monitors or control screens in an embedded industrial application which employ a real-time operating system (RTOS).

Cell phones and handheld game systems also employ application specific touchscreen GUIs. Newer automobiles use GUIs in their navigation systems and multimedia centers, or navigation multimedia center combinations.

Components

A GUI uses a combination of technologies and devices to provide a platform that users can interact with, for the tasks of gathering and producing information.

A series of elements conforming a visual language have evolved to represent information stored in computers. This makes it easier for people with few computer skills to work with and use computer software. The most common combination of such elements in GUIs is the windows, icons, text fields, canvases, menus, pointer (WIMP) paradigm, especially in personal computers.

The WIMP style of interaction uses a virtual input device to represent the position of a pointing device's interface, most often a mouse, and presents information organized in windows and represented with icons. Available commands are compiled together in menus, and actions are performed making gestures with the pointing device. A window manager facilitates the interactions between windows, applications, and the windowing system. The windowing system handles hardware devices such as pointing devices, graphics hardware, and positioning of the pointer.

In personal computers, all these elements are modeled through a desktop metaphor to produce a simulation called a desktop environment in which the display represents a desktop, on which documents and folders of documents can be placed. Window managers and other software combine to simulate the desktop environment with varying degrees of realism.

Entries may appear in a list to make space for text and details, or in a grid for compactness and larger icons with little space underneath for text. Variations inbetween exist, such as a list with multiple columns of items and a grid of items with rows of text extending sideways from the icon.

Multi-row and multi-column layouts commonly found on the web are "shelf" and "waterfall". The former is found on image search engines, where images appear with a fixed height but variable length, and is typically implemented with the CSS property and parameter. A waterfall layout found on Imgur and TweetDeck with fixed width but variable height per item is usually implemented by specifying.

Post-WIMP interface
Smaller app mobile devices such as personal digital assistants (PDAs) and smartphones typically use the WIMP elements with different unifying metaphors, due to constraints in space and available input devices. Applications for which WIMP is not well suited may use newer interaction techniques, collectively termed post-WIMP UIs.

As of 2011, some touchscreen-based operating systems such as Apple's iOS (iPhone) and Android use the class of GUIs named post-WIMP. These support styles of interaction using more than one finger in contact with a display, which allows actions such as pinching and rotating, which are unsupported by one pointer and mouse.

Interaction
Human interface devices, for the efficient interaction with a GUI include a computer keyboard, especially used together with keyboard shortcuts, pointing devices for the cursor (or rather pointer) control: mouse, pointing stick, touchpad, trackball, joystick, virtual keyboards, and head-up displays (translucent information devices at the eye level).

There are also actions performed by programs that affect the GUI. For example, there are components like inotify or D-Bus to facilitate communication between computer programs.

Early efforts
Ivan Sutherland developed Sketchpad in 1963, widely held as the first graphical computer-aided design program. It used a light pen to create and manipulate objects in engineering drawings in realtime with coordinated graphics. In the late 1960s, researchers at the Stanford Research Institute, led by Douglas Engelbart, developed the On-Line System (NLS), which used text-based hyperlinks manipulated with a then-new device: the mouse. (A 1968 demonstration of NLS became known as "The Mother of All Demos".) In the 1970s, Engelbart's ideas were further refined and extended to graphics by researchers at Xerox PARC and specifically Alan Kay, who went beyond text-based hyperlinks and used a GUI as the main interface for the Smalltalk programming language, which ran on the Xerox Alto computer, released in 1973. Most modern general-purpose GUIs are derived from this system.

The Xerox PARC GUI consisted of graphical elements such as windows, menus, radio buttons, and check boxes. The concept of icons was later introduced by David Canfield Smith, who had written a thesis on the subject under the guidance of Kay. The PARC GUI employs a pointing device along with a keyboard. These aspects can be emphasized by using the alternative term and acronym for windows, icons, menus, pointing device (WIMP). This effort culminated in the 1973 Xerox Alto, the first computer with a GUI, though the system never reached commercial production.

The first commercially available computer with a GUI was the 1979 PERQ workstation, manufactured by Three Rivers Computer Corporation. Its design was heavily influenced by the work at Xerox PARC. In 1981, Xerox eventually commercialized the ideas from the Alto in the form of a new and enhanced system – the Xerox 8010 Information System – more commonly known as the Xerox Star. These early systems spurred many other GUI efforts, including Lisp machines by Symbolics and other manufacturers, the Apple Lisa (which presented the concept of menu bar and window controls) in 1983, the Apple Macintosh 128K in 1984, and the Atari ST with Digital Research's GEM, and Commodore Amiga in 1985. Visi On was released in 1983 for the IBM PC compatible computers, but was never popular due to its high hardware demands. Nevertheless, it was a crucial influence on the contemporary development of Microsoft Windows.

Apple, Digital Research, IBM and Microsoft used many of Xerox's ideas to develop products, and IBM's Common User Access specifications formed the basis of the GUIs used in Microsoft Windows, IBM OS/2 Presentation Manager, and the Unix Motif toolkit and window manager. These ideas evolved to create the interface found in current versions of Microsoft Windows, and in various desktop environments for Unix-like operating systems, such as macOS and Linux. Thus most current GUIs have largely common idioms.

Popularization
GUIs were a hot topic in the early 1980s. The Apple Lisa was released in 1983, and various windowing systems existed for DOS operating systems (including PC GEM and PC/GEOS). Individual applications for many platforms presented their own GUI variants. Despite the GUIs advantages, many reviewers questioned the value of the entire concept, citing hardware limits, and problems in finding compatible software.

In 1984, Apple released a television commercial which introduced the Apple Macintosh during the telecast of Super Bowl XVIII by CBS, with allusions to George Orwell's noted novel Nineteen Eighty-Four. The goal of the commercial was to make people think about computers, identifying the user-friendly interface as a personal computer which departed from prior business-oriented systems, and becoming a signature representation of Apple products.

In 1985, Commodore released the Amiga 1000, along with Workbench and Kickstart 1.0 (which contained Intuition). This interface ran as a separate task, meaning it was very responsive and, unlike other GUIs of the time, it didn't freeze up when a program was busy. Additionally, it was the first GUI to introduce something resembling Virtual Desktops.

Windows 95, accompanied by an extensive marketing campaign, was a major success in the marketplace at launch and shortly became the most popular desktop operating system.

In 2007, with the iPhone and later in 2010 with the introduction of the iPad, Apple popularized the post-WIMP style of interaction for multi-touch screens, and those devices were considered to be milestones in the development of mobile devices.

The GUIs familiar to most people as of the mid-late 2010s are Microsoft Windows, macOS, and the X Window System interfaces for desktop and laptop computers, and Android, Apple's iOS, Symbian, BlackBerry OS, Windows Phone/Windows 10 Mobile, Tizen, WebOS, and Firefox OS for handheld (smartphone) devices.

Command-line interfaces
Since the commands available in command line interfaces can be many, complex operations can be performed using a short sequence of words and symbols. Custom functions may be used to facilitate access to frequent actions. Command-line interfaces are more lightweight, as they only recall information necessary for a task; for example, no preview thumbnails or graphical rendering of web pages. This allows greater efficiency and productivity once many commands are learned. But reaching this level takes some time because the command words may not be easily discoverable or mnemonic. Also, using the command line can become slow and error-prone when users must enter long commands comprising many parameters or several different filenames at once. However, windows, icons, menus, pointer (WIMP) interfaces present users with many widgets that represent and can trigger some of the system's available commands.

GUIs can be made quite hard when dialogs are buried deep in a system or moved about to different places during redesigns. Also, icons and dialog boxes are usually harder for users to script.

WIMPs extensively use modes, as the meaning of all keys and clicks on specific positions on the screen are redefined all the time. Command-line interfaces use modes only in limited forms, such as for current directory and environment variables.

Most modern operating systems provide both a GUI and some level of a CLI, although the GUIs usually receive more attention.

GUI wrappers
GUI wrappers find a way around the command-line interface versions (CLI) of (typically) Linux and Unix-like software applications and their text-based UIs or typed command labels. While command-line or text-based applications allow users to run a program non-interactively, GUI wrappers atop them avoid the steep learning curve of the command-line, which requires commands to be typed on the keyboard. By starting a GUI wrapper, users can intuitively interact with, start, stop, and change its working parameters, through graphical icons and visual indicators of a desktop environment, for example. Applications may also provide both interfaces, and when they do the GUI is usually a WIMP wrapper around the command-line version. This is especially common with applications designed for Unix-like operating systems. The latter used to be implemented first because it allowed the developers to focus exclusively on their product's functionality without bothering about interface details such as designing icons and placing buttons. Designing programs this way also allows users to run the program in a shell script.

Three-dimensional graphical user interface
Many environments and games use the methods of 3D graphics to project 3D GUI objects onto the screen. The use of 3D graphics has become increasingly common in mainstream operating systems (ex. Windows Aero, and Aqua (MacOS)) to create attractive interfaces, termed eye candy (which includes, for example, the use of drop shadows underneath windows and the cursor), or for functional purposes only possible using three dimensions. For example, user switching is represented by rotating a cube with faces representing each user's workspace, and window management is represented via a Rolodex-style flipping mechanism in Windows Vista (see Windows Flip 3D). In both cases, the operating system transforms windows on-the-fly while continuing to update the content of those windows.

The GUI is usually WIMP-based, although occasionally other metaphors surface, such as those used in Microsoft Bob, 3dwm, File System Navigator, File System Visualizer, 3D Mailbox, and GopherVR. Zooming (ZUI) is a related technology that promises to deliver the representation benefits of 3D environments without their usability drawbacks of orientation problems and hidden objects. In 2006, Hillcrest Labs introduced the first ZUI for television. Other innovations include the menus on the PlayStation 2, the menus on the Xbox, Sun's Project Looking Glass, Metisse, which was similar to Project Looking Glass, BumpTop, where users can manipulate documents and windows with realistic movement and physics as if they were physical documents, Croquet OS, which is built for collaboration, and compositing window managers such as Enlightenment and Compiz. Augmented reality and virtual reality also make use of 3D GUI elements.

In science fiction
3D GUIs have appeared in science fiction literature and films, even before certain technologies were feasible or in common use.

 * In prose fiction, 3D GUIs have been portrayed as immersible environments, coined as William Gibson's "cyberspace" and Neal Stephenson's "metaverse" and "avatars".
 * The 1993 American film Jurassic Park features Silicon Graphics' 3D file manager File System Navigator, a real-life file manager for Unix operating systems.
 * The film Minority Report has scenes of police officers using specialized 3D data systems.

Gamete

A gamete (, ultimately ) is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. Gametes are an organism's reproductive cells, also referred to as sex cells. The name gamete was introduced by the German cytologist Eduard Strasburger in 1878.

Gametes of both mating individuals can be the same size and shape, a condition known as isogamy. By contrast, in the majority of species, the gametes are of different sizes, a condition known as anisogamy or heterogamy that applies to humans and other mammals. The human ovum has approximately 100,000 times the volume of a single human sperm cell. The type of gamete an organism produces determines its sex and sets the basis for the sexual roles and sexual selection. In humans and other species that produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual that produces the larger type of gamete called an ovum, and a male produces the smaller type, called a sperm cell or spermatozoon. Sperm cells are small and motile due to the presence of a tail-shaped structure, the flagellum, that provides propulsion. In contrast, each egg cell or ovum is relatively large and non-motile.

Oogenesis, the process of female gamete formation in animals, involves meiosis (including meiotic recombination) of a diploid primary oocyte to produce a haploid ovum. Spermatogenesis, the process of male gamete formation in animals, involves meiosis in a diploid primary spermatocyte to produce haploid spermatozoa. In animals, ova are produced in the ovaries of females and sperm develop in the testes of males. During fertilization, a spermatozoon and an ovum, each carrying half of the genetic information of an individual, unite to form a zygote that develops into a new diploid organism.

Evolution
It is generally accepted that isogamy is the ancestral state from which anisogamy and oogamy evolved, although its evolution has left no fossil records. There are almost invariably only two gamete types, all analyses showing that intermediate gamete sizes are eliminated due to selection. Since intermediate sized gametes do not have the same advantages as small or large ones, they do worse than small ones in mobility and numbers, and worse than large ones in supply.

Differences between gametes and somatic cells
In contrast to a gamete, which has only one set of chromosomes, a diploid somatic cell has two sets of homologous chromosomes, one of which is a copy of the chromosome set from the sperm and one a copy of the chromosome set from the egg cell. Recombination of the genes during meiosis ensures that the chromosomes of gametes are not exact duplicates of either of the sets of chromosomes carried in the parental diploid chromosomes but a mixture of the two.

Artificial gametes
Artificial gametes, also known as in vitro derived gametes (IVD), stem cell-derived gametes (SCDGs), and in vitro generated gametes (IVG), are gametes derived from stem cells. The use of such artificial gametes would "necessarily require IVF techniques". Research shows that artificial gametes may be a reproductive technique for same-sex male couples, although a surrogate mother would still be required for the gestation period. Women who have passed menopause may be able to produce eggs and bear genetically related children with artificial gametes. Robert Sparrow wrote, in the Journal of Medical Ethics, that embryos derived from artificial gametes could be used to derive new gametes and this process could be repeated to create multiple human generations in the laboratory. This technique could be used to create cell lines for medical applications and for studying the heredity of genetic disorders. Additionally, this technique could be used for human enhancement by selectively breeding for a desired genome or by using recombinant DNA technology to create enhancements that have not arisen in nature.

Plants
Plants that reproduce sexually also produce gametes. However, since plants have a life cycle involving alternation of diploid and haploid generations some differences from animal life cycles exist. Plants use meiosis to produce spores that develop into multicellular haploid gametophytes which produce gametes by mitosis. In animals there is no corresponding multicellular haploid phase. The sperm of plants that reproduce using spores are formed by mitosis in an organ of the gametophyte known as the antheridium and the egg cells by mitosis in a flask-shaped organ called the archegonium. Plant sperm cells are their only motile cells, often described as flagellate, but more correctly as ciliate. Bryophytes have 2 flagella, horsetails have up to 200 and the mature spermatozoa of the cycad Zamia pumila has up to 50,000 flagella. Cycads and Ginkgo biloba are the only gymnosperms with motile sperm. In the flowering plants, the female gametophyte is produced inside the ovule within the ovary of the flower. When mature, the haploid gametophyte produces female gametes which are ready for fertilization. The male gametophyte is produced inside a pollen grain within the anther and is non-motile, but can be distributed by wind, water or animal vectors. When a pollen grain lands on a mature stigma of a flower it germinates to form a pollen tube that grows down the style into the ovary of the flower and then into the ovule. The pollen then produces non-motile sperm nuclei by mitosis that are transported down the pollen tube to the ovule where they are released for fertilization of the egg cell.

George R. R. Martin

George Raymond Richard Martin (born George Raymond Martin; September 20, 1948), also known by his initials G.R.R.M., is an American author, television writer, and television producer. He is best known as the author of the series of epic fantasy novels A Song of Ice and Fire, which were adapted into the Primetime Emmy Award–winning television series Game of Thrones (2011–2019) and its prequel series House of the Dragon (2022–present). He also helped create the Wild Cards anthology series, and contributed worldbuilding for the video game Elden Ring (2022).

In 2005, Lev Grossman of Time called Martin "the American Tolkien",  and in 2011, he was included on the annual Time 100 list of the most influential people in the world. He is a longtime resident of Santa Fe, New Mexico, where he helped fund Meow Wolf and owns the Jean Cocteau Cinema. The city commemorates March 29 as George R. R. Martin Day.

Early life
George Raymond Martin (he adopted the confirmation name Richard at 13 years old) was born on September 20, 1948, in Bayonne, New Jersey, the son of longshoreman Raymond Collins Martin and Margaret Brady Martin. His mother's family had once been wealthy, owning a successful construction business, but lost it all in the Great Depression, something Martin was reminded about every day when he passed what used to be his family's dock and house. He has two younger sisters, Darleen and Jane. He is predominantly of Irish descent; a DNA test on the series Finding Your Roots showed him to be 53.6% "British and Irish", 22.4% Ashkenazi Jewish, and 15.6% "Broadly Northwestern European".

The family first lived in a house on Broadway belonging to Martin's great-grandmother. In 1953, they moved to a federal housing project near the Bayonne docks. During Martin's childhood, his world consisted predominantly of "First Street to Fifth Street", between his grade school and his home. This limited world made him want to travel and experience other places, but the only way of doing so was through his imagination, and he became a voracious reader.

Martin began writing and selling monster stories for pennies to other neighborhood children, dramatic readings included. He had to stop once a customer's mother complained about her child's nightmares. He also wrote stories about a mythical kingdom populated by his pet turtles — the turtles died frequently in their toy castle, so he decided they were killing each other off in "sinister plots". Martin had a habit of starting "endless stories" that he never completed, as they did not turn out as well on paper as he had imagined them.

Martin attended Mary Jane Donohoe School and later Marist High School. While there, he became an avid comic-book fan, developing a strong interest in the superheroes being published by Marvel Comics, and later credited Stan Lee for being one of his greatest literary influences; "Maybe Stan Lee is the greatest literary influence on me, even more than Shakespeare or Tolkien." A letter Martin wrote to the editor of Fantastic Four was printed in issue #20 (November 1963); it was the first of many sent, e.g., Fantastic Four #32, #34, and others. Fans who read his letters wrote him letters in turn, and through such contacts, Martin joined the fledgling comics fandom of the era, writing fiction for various fanzines; he bought the first ticket to the world's first Comic-Con, held in New York in 1964. In 1965, Martin won comic fandom's Alley Award for Best Fan Fiction for his prose superhero story "Powerman vs. The Blue Barrier".

In 1970, Martin earned a B.S. in journalism with a minor in history from Northwestern University's Medill School of Journalism in Evanston, Illinois, graduating summa cum laude; he went on to complete his M.S. in Journalism in 1971, also from Medill. Eligible for the draft during the Vietnam War, to which he objected, Martin applied for and obtained conscientious objector status; he instead did alternative service work for two years (1972–1974) as a VISTA volunteer, attached to the Cook County Legal Assistance Foundation.

Early writing career
Martin began selling science fiction short stories professionally in 1970, at age 21. His first sale was "The Hero", sold to Galaxy magazine and published in its February 1971 issue; other sales soon followed. His first story to be nominated for the Hugo Award and Nebula Awards was "With Morning Comes Mistfall", published in 1973 in Analog magazine. In 1975 his story "...for a single yesterday" about a post-apocalyptic timetripper was selected for inclusion in Epoch, a science fiction anthology edited by Roger Elwood and Robert Silverberg. His first novel, Dying of the Light, was completed in 1976 right before he moved to Dubuque and published in 1977. That same year the enormous success of Star Wars had a huge impact on the publishing industry and science fiction, and he sold the novel for the same amount he would make in three years of teaching.

The short stories he was able to sell in his early 20s gave him some profit but not enough to pay his bills, which prevented him from becoming the full-time writer he wanted to be. The need for a day job occurred simultaneously with the American chess craze which followed Bobby Fischer's victory in the 1972 world chess championship. Martin's own chess skills and experience allowed him to be hired as a tournament director for the Continental Chess Association, which ran chess tournaments on the weekends. This gave him a sufficient income, and because the tournaments only ran on Saturdays and Sundays, it allowed him to work as a writer five days a week from 1973 to 1976. By the time the chess craze subsided and no longer provided an income, he had become much better established as a writer.

Teaching
In the mid-1970s, Martin met English professor George Guthridge from Dubuque, Iowa, at a science fiction convention in Milwaukee. Martin persuaded Guthridge (who later said that at that time he despised science fiction and fantasy) not only to give speculative fiction a second look, but also to write in the field himself. Guthridge has since been a finalist for the Hugo Award and twice for the Nebula Award for science fiction and fantasy. In 1998, Guthridge and Janet Berliner won the Bram Stoker Award for Superior Achievement in the Novel for their Children of the Dusk.

In turn, Guthridge helped Martin in finding a job at Clarke University (then Clarke College). Martin "wasn't making enough money to stay alive" from writing and the chess tournaments, says Guthridge. From 1976 to 1978, Martin was an English and journalism instructor at Clarke, and he became Writer In Residence at the college from 1978 to 1979.

Concentration on writing
While he enjoyed teaching, the sudden death of friend and fellow author Tom Reamy in late 1977 made Martin reevaluate his own life, and he eventually decided to try to become a full-time writer. In 1979 he resigned from his job and moved from Dubuque to Santa Fe, New Mexico at the end of the year. There he would live alone for almost three years, a period he described as tremendously productive in regard of writing.

Martin is a member of the Science Fiction and Fantasy Writers of America (SFWA); he served as the organization's Southwest Regional Director from 1977 to 1979, and as its vice-president from 1996 to 1998. In 1976, for Kansas City's MidAmeriCon, the 34th World Science Fiction Convention (Worldcon), Martin and his friend and fellow writer-editor Gardner Dozois conceived of and organized the first Hugo Losers' Party for the benefit of all past and present Hugo-losing writers on the evening following the convention's Hugo Awards ceremony. Martin was nominated for two Hugos that year but lost both awards, for the novelette "...and Seven Times Never Kill Man" and the novella The Storms of Windhaven, co-written with Lisa Tuttle. Although Martin often writes fantasy or horror, a number of his earlier works are science fiction tales occurring in a loosely defined future history, known informally as "The Thousand Worlds" or "The Manrealm".

In 2017, Martin recalled that he had started writing science fiction-horror hybrids in the late 1970s to disprove a statement from a critic claiming that science fiction and horror were opposites and therefore incompatible. Martin considered Sandkings (1979) the best known of these. Another was the novella Nightflyers (1980), whose screen and television rights were purchased by Vista in 1984, which produced a 1987 film adaptation, Nightflyers, with a screenplay co-written by Martin. Martin was unhappy about having to cut plot elements in order to accommodate the film's small budget. While not a hit at theatres, Martin believes that the film saved his career, and that everything he has written since exists in large part because of it. He has also written at least one piece of political-military fiction, "Night of the Vampyres", collected in Harry Turtledove's anthology The Best Military Science Fiction of the 20th Century (2001).

In 1982, Martin published a vampire novel titled Fevre Dream set in the 19th century on the Mississippi River. Unlike traditional vampire novels, in Fevre Dream vampires are not supernatural creatures, but are rather a different species related to humans created by evolution with superhuman powers. Critic Don D'Amassa has praised Fevre Dream for its strong 19th-century atmosphere and wrote: "This is without question one of the greatest vampire novels of all time". Martin followed up Fevre Dream with another horror novel, The Armageddon Rag (1983). The unexpected commercial failure of The Armageddon Rag "essentially destroyed my career as a novelist at the time", he recalled, and made him consider going into real estate instead.

In 1984, the new editor of Baen Books, Betsy Mitchell, called Martin to ask him if he had considered doing a collection of Haviland Tuf adventures. Martin, who had several favorite series characters like Solomon Kane, Elric, Nicholas van Rijn and Magnus Ridolph, had made an attempt to create such a character on his own in the 1970s with his Tuf stories. He was interested, but was too occupied with the writing of his next book, the never-completed novel Black and White and Red All Over, which occupied most of his writing time the same year. But after the failure of The Armageddon Rag, all editors rejected his upcoming novel, and desperate for money, he accepted Mitchell's offer and wrote some more Tuf stories which were collected in Tuf Voyaging, which sold well enough for Mitchell to suggest a sequel. Martin was willing and agreed to do it, but before he got started he got an offer from Hollywood, where producer Philip DeGuere Jr. wanted to adapt The Armageddon Rag into a film. The film adaptation did not happen, but they stayed in touch, and when DeGuere became the producer for the revival of The Twilight Zone, Martin was offered a job as a writer. Working for television paid a lot better than writing literature, so he decided to move to Hollywood to seek a new career. At first he worked as staff writer for the show, and then as an executive story consultant.

After the CBS series was cancelled, Martin migrated over to the already-underway satirical science fiction series Max Headroom. He worked on scripts and created the show's "Ped Xing" character. However, before his scripts could go into production, the ABC show was cancelled in the middle of its second season. Martin was hired as a writer-producer on the new dramatic fantasy series Beauty and the Beast; in 1989, he became the show's co-supervising producer and wrote 14 of its episodes.

In 1987, Martin published a collection of short horror stories in Portraits of His Children. During this same period, Martin continued working in print media as a book-series editor, this time overseeing the development of the multi-author Wild Cards book series, which takes place in a shared universe in which a small slice of post–World War II humanity gains superpowers after the release of an alien-engineered virus; new titles are published in the ongoing series from Tor Books. In Second Person, Martin "gives a personal account of the close-knit role-playing game (RPG) culture that gave rise to his Wild Cards shared-world anthologies". An important element in the creation of the multiple-author series was a campaign of Chaosium's role-playing game Superworld (1983) that Martin ran in Albuquerque. Admitting he became completely obsessed with the game, he stopped writing literature for most of 1983, which he refers to as his "lost year", but his shrinking bank accounts made him realize he had to come up with something, and got the idea that perhaps the stories and characters created in Superworld could somehow become profitable. Martin's own contributions to Wild Cards have included Thomas Tudbury, "The Great and Powerful Turtle", a powerful psychokinetic whose flying "shell" consisted of an armored VW Beetle. , 21 Wild Cards volumes had been published in the series; earlier that same year, Martin signed the contract for the 22nd volume, Low Ball (2014), published by Tor Books. In early 2012, Martin signed another Tor contract for the 23rd Wild Cards volume, High Stakes, which was released in August 2016.

In August 2016, Martin announced that Universal Cable Productions had acquired the rights to adapt the Wild Cards novels into a television series. He noted that he himself would not write for the adaptation due to focusing on A Song of Ice and Fire.

A Song of Ice and Fire
In 1991, Martin briefly returned to writing novels. He had grown frustrated that his TV pilots and screenplays were not getting made and that TV-related production limitations like budgets and episode lengths were forcing him to cut characters and trim battle scenes. This pushed Martin back towards writing books, where he did not have to worry about compromising his imagination. Admiring the works of J. R. R. Tolkien in his childhood, he wanted to write an epic fantasy, though he did not have any specific ideas.

His epic fantasy series, A Song of Ice and Fire, was inspired by the Wars of the Roses, The Accursed Kings and Ivanhoe. Though Martin originally conceptualized it as being three volumes, it is currently slated to comprise seven. The first, A Game of Thrones, was published in 1996, followed by A Clash of Kings in 1998 and A Storm of Swords in 2000. In November 2005, A Feast for Crows, the fourth novel in this series, became The New York Times No. 1 Bestseller. The fifth book, A Dance with Dragons, was published July 12, 2011, and became an international bestseller, including achieving a No. 1 spot on the New York Times Bestseller List and many others; it remained on the New York Times list for 88 weeks.

In 2012, A Dance With Dragons made the final ballot for science fiction and fantasy's Hugo Award, World Fantasy Award, Locus Poll Award, and the British Fantasy Award; the novel went on to win the Locus Poll Award for Best Fantasy Novel. Two more novels are planned in the series: The Winds of Winter and the final volume A Dream of Spring.

On April 25, 2018, Martin announced the release date of his new book, Fire & Blood, dealing with the history of House Targaryen, which was released on November 20, 2018. Should Martin die before finishing the A Song of Ice and Fire series, former collaborators have said that they will not conclude the series for him.

HBO adaptation of A Song of Ice and Fire
HBO Productions purchased the television rights for the A Song of Ice and Fire series in 2007. Although busy completing A Dance With Dragons and other projects, George R. R. Martin was heavily involved in the production of the television series adaptation of his books. Martin's involvement included the selection of a production team and participation in scriptwriting; the opening credits list him as a co-executive producer of the series. The original pilot was shot between October 24 and November 19, 2009, on location in Northern Ireland, Scotland and Morocco. It was received so poorly by HBO executives that they did not make a decision for four months after the pilot was delivered. In March 2010, HBO's decision to greenlight the series was announced, with the production of the series scheduled to start June 2010. HBO however demanded the first episode be reshot, and wanted all the scenes from Morocco scrapped. The first episode ("Winter Is Coming") premiered on HBO in the United States and Canada on April 17, 2011. It was seen initially by 2.2 million viewers. The first season was nominated for 13 Emmy Awards, ultimately winning two: one for its opening title credits, and one for Peter Dinklage as Best Supporting Actor.

HBO ordered a second season of Game of Thrones on April 19, 2011, two days after the series premiere. The second season obtained a 15% increase in budget in order to be able to stage the war's most important battle, the Battle of the Blackwater, in episode nine which was written by George R. R. Martin. Filming took place during 106 shooting days. During three-quarters of those, two crews ("Dragon" and "Wolf") were working simultaneously in different locations. Alan Taylor was promoted to co-executive producer and directed four episodes, including the season premiere and finale. David Petrarca and David Nutter each directed two episodes, while series cinematographer Alik Sakharov and filmmaker Neil Marshall directed the remaining two. The second season premiered in the United States on HBO on April 1, 2012, and concluded on June 3, 2012. U.S. viewership rose by approximately 8% over the course of the season, from 3.9 million to 4.2 million by the season finale. The second season won six of the twelve Emmy Awards for which it was nominated.

Game of Thrones rapidly became a critical and commercial success after the second season. HBO renewed the series for a third season on April 10, 2012, nine days after the second season's premiere. Production began in July 2012 and concluded with the wrap of the unit filming in Iceland on November 24, 2012. The third season is based on the first half of the novel A Storm of Swords. Benioff had previously said that A Storm of Swords would need to be adapted in two seasons on account of its length. Benioff and Weiss also noted that they thought of Game of Thrones as an adaptation of the series as a whole, rather than of individual novels, which gave them the liberty to move scenes back and forth across novels according to the requirements of the screen adaptation. Season 3 saw the first significant use of the Valyrian languages, spoken in doomed Valyria and its former colonies in Essos. The constructed languages were developed by linguist David J. Peterson based on the few words Martin invented for the novels. Peterson had previously developed the Dothraki language, used principally in season 1. The third season premiered on HBO on March 31, 2013, and concluded on June 9, 2013. The third season was seen by 14.2 million viewers. It won 2 of the 16 Emmy Awards for which it was nominated.

Two days after third season premiere, HBO ordered the fourth season on April 2, 2013, which began filming in July 2013. The season is adapted primarily from the second half of A Storm of Swords, along with elements of A Feast for Crows and A Dance with Dragons. Showrunners David Benioff and D. B. Weiss co-wrote seven out of ten episodes. The remaining three episodes were written by Bryan Cogman (two episodes), and George R. R. Martin (one episode). For this season, the filming lasted 136 days and was completed on November 21, 2013. The fourth season premiered in the United States on HBO on April 6, 2014, and concluded on June 15, 2014. The season was met with largely positive reviews. It won 4 of the 19 Emmy Awards for which it was nominated. With its fourth season, Game of Thrones has become the most-watched HBO series in history (surpassing the fourth season of The Sopranos which had a gross audience of 18.2 million viewers), averaging 18.4 million viewers across multiple platforms, including live viewing, encores, DVR views, HBO GO and On Demand views.

Up until the fourth season, Martin wrote one episode for each season. In 2022, Martin said that he had been estranged from the show during the production process of the last 4 seasons (starting with season 5). In the early seasons, Martin wrote and read scripts, consulted on casting decisions and visited sets. Over time, however, he stepped back to focus on his long-delayed next "Thrones" novel, The Winds of Winter. Following the gargantuan success of the fourth season, HBO ordered the fifth season on April 8, 2014, together with the sixth season, which began filming in July 2014. The season primarily adapts the storylines from A Feast for Crows and A Dance with Dragons, also with original content not found in Martin's novels. This season set a Guinness World Record for winning the highest number of Emmy Awards for a series in a single season and year, winning 12 out of 24 nominations, including Outstanding Drama Series.

With a budget over $100 million for the whole season, filming for the sixth season began in July 2015 and ended on December. The season filmed in five different countries: Northern Ireland, Spain, Croatia, Iceland, and Canada. This season saw the overall plot of the show diverging from the source material. Some of the season's storyline is derived from content not yet published in Martin's A Song of Ice and Fire series, although a significant amount of material from A Feast for Crows, A Dance with Dragons and the upcoming sixth novel The Winds of Winter, which Martin previously outlined to showrunners David Benioff and D.B. Weiss, was used. The season was largely met with positive reviews. The "Battle of the Bastards" episode received immense critical acclaim, with many calling it one of the best television episodes of all time. U.S. viewership rose compared to the previous season, and by approximately 13 percent over its course, from 7.9 million to 8.9 million by the finale. The season won 12 of the 23 Emmy Awards for which it was nominated.

Three days before the premiere of the episode "The Red Woman", HBO ordered the seventh season. Due to necessary weather conditions required for filming, the production of the penultimate season of the show was delayed that year. Filming began only on August 31, 2016, at Titanic Studios in Belfast, and ended in February 2017. Unlike previous seasons, the seventh and eighth seasons largely consisted of original content not found in the source material. This season comprised only seven episodes. The showrunners stated that they were unable to produce 10 episodes in the show's usual 12 to 14 month time frame, as Weiss said "It's crossing out of a television schedule into more of a mid-range movie schedule". The average runtime of an episode in this season was approximately 63 minutes. The series received 22 nominations for the 70th Primetime Emmy Awards and won 9 of them, including "Outstanding Drama Series".

Unlike its prior seasons, the final one took a year gap for its production and filming. The eighth season consisted of only six episodes, though the average runtime of an episode was 68 minutes, the longest of all seasons, with "The Long Night" consisting of 81 minutes. The season was met with mixed reviews from critics. While the performances, production values and music score were praised, criticism was mainly directed at the shorter runtime of the season as well as numerous creative decisions made by the showrunners. Many commentators deemed it to be a disappointing conclusion to the series. The season received 32 nominations at the 71st Primetime Emmy Awards, the most for a single season of television in history. It won twelve, including Outstanding Drama Series and Outstanding Supporting Actor in a Drama Series for Peter Dinklage.

Three years after the show ended, a prequel series, House of the Dragon, premiered on HBO in August 21, 2022. Based on parts of the novel Fire & Blood, the series is set about 200 years before the events of Game of Thrones. Ryan Condal and Miguel Sapochnik served as the showrunners for the first season. Five days after its premiere, the series was renewed for a second season by HBO. On September 1, Sapochnik departed as showrunner, with another veteran Game of Thrones director Alan Taylor replacing him as the co-showrunner for the upcoming second season.

In June 2022, it was reported that a Jon Snow sequel series with Kit Harington to reprise his role was in early development at HBO. The working title is Snow and Martin confirmed his involvement with the project and that Harington initiated the idea. Also in June, Martin said there were still three other live-action series in development: 10,000 Ships (written by Amanda Segal), 9 Voyages aka Sea Snake (written by Bruno Heller), and the Dunk & Egg prequel series (written by Steven Conrad), tentatively titled either The Hedge Knight or Knight of the Seven Kingdoms.

In January 2021, an animated drama series was announced as in development at HBO Max. In July 2021, two more animated series were in development at HBO Max, with one being set in Yi Ti, a nation in Essos loosely based on Imperial China.

Themes
Martin's work has been described as having "complex story lines, fascinating characters, great dialogue, perfect pacing" by literary critic Jeff VanderMeer. Dana Jennings of the New York Times described Martin's work as "fantasy for grown ups" and Lev Grossman wrote that it was dark and cynical. Martin's first novel, Dying of the Light, set the tone for some of his future work; it unfolds on a mostly abandoned planet that is slowly becoming uninhabitable as it moves away from its sun. This story has a strong sense of melancholy. His characters are often unhappy or, at least, unsatisfied, in many cases holding on to idealisms in spite of an otherwise chaotic and ruthless world, and often troubled by their own self-seeking or violent actions, even as they undertake them. Many have elements of tragic heroes or antiheroes in them; reviewer T. M. Wagner writes: "Let it never be said Martin doesn't share Shakespeare's fondness for the senselessly tragic." The overall gloominess of A Song of Ice and Fire can be an obstacle for some readers; the Inchoatus Group writes that, "If this absence of joy is going to trouble you, or you're looking for something more affirming, then you should probably seek elsewhere." However, for many fans, it is precisely this level of "realness" and "completeness" – including many characters' imperfections, moral and ethical ambiguity, and (often sudden) consequential plot twists that is endearing about Martin's work. Many find that this is what makes the series' story arcs compelling enough to keep following despite its sheer brutality and intricately messy and interwoven plotlines; as TM Wagner points out:"There's great tragedy here, but there's also excitement, humor, heroism even in weaklings, nobility even in villains, and, now and then, a taste of justice after all. It's a rare gift when a writer can invest his story with that much humanity."Martin's characters are multifaceted, each with intricate pasts, aspirations, and ambitions. Publishers Weekly writes of his ongoing epic fantasy A Song of Ice and Fire: "The complexity of characters such as Daenerys, Arya and the Kingslayer will keep readers turning even the vast number of pages contained in this volume, for the author, like Tolkien or Jordan, makes us care about their fates." Misfortune, injury, and death (including false death and reanimation) often befall major or minor characters, no matter how attached the reader has become. Martin has described his penchant for killing off important characters as being necessary for the story's depth: "when my characters are in danger, I want you to be afraid to turn the page, (so) you need to show right from the beginning that you're playing for keeps".

In distinguishing his work from others, Martin makes a point of emphasizing realism and plausible social dynamics above an over-reliance on magic and a simplistic "good versus evil" dichotomy, for which contemporary fantasy writing is often criticized. Notably, Martin's work makes a sharp departure from the prevalent "heroic knights and chivalry" schema that has become a mainstay in fantasy as derived from J. R. R. Tolkien's The Lord of the Rings. He specifically critiques the oversimplification of Tolkien's themes and devices by imitators in ways that he has humorously described as "Disneyland Middle Ages", which gloss over or ignore major differences between medieval and modern societies, particularly social structures, ways of living, and political arrangements. Martin has been described as "the American Tolkien" by literary critics. While Martin finds inspiration in Tolkien's legacy, he aims to go beyond what he sees as Tolkien's "medieval philosophy" of "if the king was a good man, the land would prosper" to delve into the complexities, ambiguities, and vagaries of real-life power: "We look at real history and it's not that simple... Just having good intentions doesn't make you a wise king." Per this fact Martin has been credited with the rise of grimdark fantasy, a modern form of an "anti-Tolkien" approach to fantasy writing which, according to British science fiction and fantasy novelist Adam Roberts, is characterized by its reaction to Tolkien's idealism even though it owes a lot to Tolkien's work. The Canadian fantasy writer R. Scott Bakker "says he wouldn't have been able to publish his fantasy novels without the success George R. R. Martin achieved first". Similarly, Mark Lawrence, author of Prince of Thorns, was inspired by Martin and impressed by his Red Wedding scene.

The author makes a point of grounding his work on a foundation of historical fiction, which he channels to evoke important social and political elements of primarily the European medieval era that differ markedly from elements of modern times, including the multigenerational, rigid, and often brutally consequential nature of the hierarchical class system of feudal societies that is in many cases overlooked in fantasy writing. Even as A Song of Ice and Fire is a fantasy series that employs magic and the surreal as central to the genre, Martin is keen to ensure that magic is merely one element of many that moves his work forward, not a generic deus ex machina that is itself the focus of his stories, which is something he has been very conscious about since reading Tolkien; "If you look at The Lord of the Rings, what strikes you, it certainly struck me, is that although the world is infused with this great sense of magic, there is very little onstage magic. So you have a sense of magic, but it's kept under very tight control, and I really took that to heart when I was starting my own series." Martin's ultimate aim is an exploration of the internal conflicts that define the human condition, which, in deriving inspiration from William Faulkner, he ultimately describes as the only reason to read any literature, regardless of genre.

In 2018, Martin called The Lord of the Rings, The Great Gatsby, Gone with the Wind, Great Expectations, Lonesome Dove, Catch-22, and Charlotte's Web "favorites all, towering masterpieces, books that changed my life".

Producing
In 2017, Martin confirmed he would serve as an executive producer of the HBO television series adaptation of the 2010 science fantasy novel Who Fears Death by Nnedi Okorafor. Martin also contributed to the 2022 video game titled Elden Ring, writing the worldbuilding aspects for it. In February 2021, it was reported that Martin and Kalinda Vazquez were developing a TV adaptation of Roadmarks by Roger Zelazny, which Martin pitched to HBO in 2020. Martin will be an executive producer, Vazquez the showrunner, writer and executive producer. In March 2021, he signed an overall deal with HBO. Martin will serve as an executive producer of the Peacock TV adaptation in development of his Wild Cards book series, together with Melinda M. Snodgrass and Vince Gerardis, Martin's manager. He will serve as an executive producer of the 2022 AMC series Dark Winds based on Tony Hillerman's Leaphorn & Chee books, together with the creator Graham Roland, the showrunner Vince Calandra, the lead Zahn McClarnon, Kiowa Gordon, Chris Eyre, Robert Redford, Tina Elmo and Vince Gerardis. In 2021, Martin served as one of the producers of the short film Night of the Cooters based on the eponymous short story by Howard Waldrop.

Relationship with fans
Martin actively contributes to his blog, Not a Blog; in April 2018, he moved his blog from Livejournal to his own website.

Martin's official fan club is the "Brotherhood Without Banners", which has a regular posting board at the Forum of the website westeros.org, which is focused on his A Song of Ice and Fire fantasy series. At the annual World Science Fiction Convention every year, the Brotherhood Without Banners hosts a large, on-going hospitality suite that is open to all members of the Worldcon.

Martin is opposed to fan fiction, which he views as copyright infringement and a bad exercise for aspiring writers in terms of developing skills in worldbuilding and character development.

Conventions
Martin is known for his regular attendance at science fiction conventions and comics conventions, and his accessibility to fans. In the early 1980s, critic and writer Thomas Disch identified Martin as a member of the "Labor Day Group", writers who regularly congregated at the annual Worldcon, usually held on or around the Labor Day weekend. Since the early 1970s, he has also attended regional science fiction conventions; further, since 1986, Martin has participated annually in Albuquerque's smaller regional convention Bubonicon, near his New Mexico home. He was the Guest of Honor at the 61st World Science Fiction Convention in Toronto, held in 2003.

In December 2016, Martin was a key speaker at the Guadalajara International Book Fair 2016 in Mexico where the author provided hints about the next two books in the series A Song of Ice and Fire.

In 2020, Martin fulfilled his duties as “toastmaster” of the Hugo Awards. During the event, he mispronounced several names, including that of R. F. Kuang, which she considered a microaggression. Martin later apologized for mispronouncing the names.

Criticism
Martin has been criticized by some of his readers for the long periods between books in the A Song of Ice and Fire series, notably the six-year gap between the fourth volume, A Feast for Crows (2005), and the fifth volume, A Dance with Dragons (2011), and the fact that The Winds of Winter, the next volume in the series, hasn't been published since. In 2010, Martin had responded to fan criticisms by saying he was unwilling to write only his A Song of Ice and Fire series, noting that working on other prose and compiling and editing different book projects have always been part of his working process.

Personal life

In the early 1970s, Martin was in a relationship with fellow science fiction/fantasy author Lisa Tuttle, with whom he co-wrote Windhaven. While attending an East Coast science fiction convention he met his first wife, Gale Burnick; they were married in 1975 and moved from their Chicago apartment and into a house in Dubuque in 1976. Both of them grew tired of the hard winters there, and when she graduated from Clarke in June 1979, he resigned from his job and they decided to move to New Mexico. The year before they had "fallen in love" with Santa Fe on their way to the worldcon in Phoenix. His wife went down and bought a house while Martin stayed behind to sell their home and finish the semester. The marriage ended in divorce in 1979, before they could be reunited in Santa Fe. Instead he settled there alone from December that same year until September 1981, when what would be his longtime partner Parris McBride moved in with him. On February 15, 2011, Martin married McBride during a small ceremony at their Santa Fe home. On August 19, 2011, they held a larger wedding ceremony and reception at Renovation, the 69th World Science Fiction Convention. They have no children.

He and McBride are supporters of the Wild Spirit Wolf Sanctuary in New Mexico. In early 2013, he purchased Santa Fe's Jean Cocteau Cinema and Coffee House, which had been closed since 2006. He had the property completely restored, including both its original 35mm capability to which was added digital projection and sound; the Cocteau officially reopened for business on August 9, 2013. In 2019, he opened a bookstore named Beastly Books, after Beauty and the Beast, next to Jean Cocteau. Martin has also supported Meow Wolf, an arts collective in Santa Fe, having pledged $2.7 million toward a new art space in January 2015.

In response to a question on his religious views, Martin replied: "I suppose I'm a lapsed Catholic. You would consider me an atheist or agnostic. I find religion and spirituality fascinating. I would like to believe this isn't the end and there's something more, but I can't convince the rational part of me that makes any sense whatsoever."

Martin is a fan of the New York Jets, the New York Giants and the New York Mets. He is also a fan of the Grateful Dead, and says that the band's music may have influenced his work.

Martin made a guest appearance as himself in an episode, "El Skeletorito", of the Adult Swim show Robot Chicken. He also appeared in SyFy's Z Nation as a zombie version of himself in season two's "The Collector", where he is still signing copies of his new novel. In Sharknado 3: Oh Hell No!, he is killed when watching a movie at the theatre.

Philanthropy
In 2014, Martin launched a campaign on Prizeo to raise funds for Wild Spirit Wolf Sanctuary and the Food Depot of Santa Fe. As part of the campaign, Martin offered one donor the chance to accompany him on a trip to the wolf sanctuary, including a helicopter ride and dinner. Martin also offered those donating $20,000 or more the opportunity to have a character named after them and "killed off" in an upcoming A Song of Ice and Fire novel. The campaign garnered media attention and raised a total of $502,549.

In 2017, Martin announced that he was funding The Miskatonic Scholarship. The Miskatonic Scholarship allows a writer of Lovecraftian cosmic horror to attend the Odyssey Writing Workshop, a six-week writing workshop held at Saint Anselm College in Manchester, New Hampshire.

Politics
Growing up, Martin avoided the draft to the Vietnam War by being a conscientious objector and did two years of alternative service. He generally opposes war and thought the Vietnam War was a "terrible mistake for America".

While he did not endorse Barack Obama in 2008, Martin endorsed him for re-election in 2012 calling Obama the most intelligent president since Jimmy Carter. In 2014, Martin endorsed Democratic Senator Tom Udall of New Mexico.

In the midst of pressure to pull the 2014 feature film The Interview from theaters, the Jean Cocteau Cinema in Santa Fe, New Mexico, which has been owned by Martin since 2013, decided to show the film. Theater manager Jon Bowman told the Santa Fe New Mexican, "Martin feels strongly about the First Amendment and the idea of artists having the ability to speak their minds and not having to worry about being targets."

Immediately following Bernie Sanders' defeat in the U.S. Democratic primary elections, he supported Democratic nominee Hillary Clinton in the general 2016 United States presidential election, and criticized Donald Trump during the election and following her defeat, commenting that Trump would "become the worst president in American history". In response to fans of Martin who compared Trump favorably to characters from A Song of Ice and Fire, Martin doubled-down on his criticism of Trump by making the case to his fans that Trump shares many personality traits in common with King Joffrey, a near-universally hated character from the series, concluding that "Trump is a Grown-Up Joffrey."

In May 2019, Martin endorsed Joe Biden for president in 2020.
