The New Wave was a science fiction style of the 1960s and 1970s, characterized by a great degree of experimentation with the form and content of stories, greater imitation of the styles of non-science fiction literature, and an emphasis on the psychological and social sciences as opposed to the physical sciences. New Wave authors often considered themselves as part of the modernist tradition of fiction, and the New Wave was conceived as a deliberate change from the traditions of the science fiction characteristic of pulp magazines, which many of the writers involved considered irrelevant or unambitious. The most prominent source of New Wave science fiction was the British magazine New Worlds, edited by Michael Moorcock, who became editor during 1964. In the United States, Harlan Ellison's 1967 anthology Dangerous Visions is often considered as the best early representation of the genre. Ursula K. Le Guin, J. G. Ballard, Samuel R. Delany, Roger Zelazny, Joanna Russ, James Tiptree Jr. (a pseudonym of Alice Bradley Sheldon), Thomas M. Disch and Brian Aldiss were also major writers associated with the style. The New Wave was influenced by postmodernism, Surrealism, the politics of the 1960s, such as the controversy concerning the Vietnam War, and by social trends such as the drug subculture, sexual liberation, and environmentalism. Although the New Wave was critiqued for the self-absorption of some of its writers, it was influential in the development of subsequent genres, primarily cyberpunk and slipstream.
