Time-travel fiction. (Genre/Form Term)

Booker, M. The science fiction handbook, 2009: p. 15 (the time-travel narrative: a paradigmatic science fictional form; the time travel motif also presents extensive opportunities for humor and satire, giving the genre a particularly wide range; indeed the flexibility of the time-travel story has made it a favorite science fiction subgenre on television and in film, as well as in the novel and short story; narratives involving travel through time represent one of the oldest subgenres in all science fiction; early examples include Irving's "Rip Van Winkle" (1819), Bellamy's utopian classic Looking Backward (1888) and Twain's A Connecticut Yankee in King Arthur's Court (1889); however the true founding text of the genre is probably Wells's classic novel The Time Machine (1895), the first genuinely science fictional exploration of time travel in book-length form)
