Although fantasy had long existed in various forms around the world before his time, J. R. R. Tolkien has been called the "father of fantasy", and The Lord of the Rings its centre. That novel, published in 1954–5, enormously influenced fantasy writing, establishing in particular the form of high or epic fantasy, set in a secondary or fantasy world in an act of mythopoeia. The book was distinctive at the time for its considerable length, its "epic" feel with a cast of heroic characters, its wide geography, and its battles. It involved an extensive history behind the action, an impression of depth, multiple sentient races and monsters, and powerful talismans. The story is a quest, with multiple subplots. The novel's success demonstrated that the genre was commercially distinct and viable.
Many later fantasy writers have either imitated Tolkien's work, or have written in reaction against it. One of the first was Ursula Le Guin's Earthsea series of novels, starting in 1968, which used Tolkienian archetypes such as wizards, a disinherited prince, a magical ring, a quest, and dragons. A publishing rush followed. Fantasy authors including Stephen R. Donaldson and Philip Pullman have created intentionally non-Tolkienian fantasies, Donaldson with an unloveable protagonist, and Pullman, who is critical of The Lord of the Rings, with a different view of the purpose of life.
The genre has spread into film, into both role-playing and video games, and into fantasy art. Peter Jackson's 2001–3 The Lord of the Rings film series brought a new and very large audience to Tolkien's work. Tolkien's influence reached role-playing games as early as 1974 with Gary Gygax's Dungeons & Dragons; this was followed by many Middle-earth video games, some directly licensed and others based on Tolkienian fantasy culture. Tolkien's fantasies have been illustrated by artists such as John Howe, Alan Lee, and Ted Nasmith, who have become known as "Tolkien artists".
