Popular novels are based entirely on the expectations for the particular genre, and this includes the creation of a series of novels with an identifiable brand name . e.g. the Sherlock Holmes series by Arthur Conan Doyle </P> <P> Popular literature holds a larger market share . Romance fiction had an estimated $1.375 billion share in the US book market in 2007 . Inspirational literature / religious literature followed with $819 million, science fiction / fantasy with $700 million, mystery with $650 million and then classic literary fiction with $466 million . </P> <P> Genre literature might be seen as the successor of the early modern chapbook . Both fields share a focus on readers who are in search of accessible reading satisfaction . The 20th - century love romance is a successor of the novels Madeleine de Scudéry, Marie de La Fayette, Aphra Behn, and Eliza Haywood wrote from the 1640s into the 1740s . The modern adventure novel goes back to Daniel Defoe's Robinson Crusoe (1719) and its immediate successors . Modern pornography has no precedent in the chapbook market but originates in libertine and hedonistic belles lettres, of works like John Cleland's Fanny Hill (1749) and similar eighteenth century novels . Ian Fleming's James Bond is a descendant of the anonymous yet extremely sophisticated and stylish narrator who mixed his love affairs with his political missions in La Guerre d'Espagne (1707). Marion Zimmer Bradley's The Mists of Avalon is influenced by Tolkien, as well as Arthurian literature, including its 19th - century successors . Modern horror fiction also has no precedent on the market of chapbooks but goes back to the elitist market of early - 19th - century Romantic literature . Modern popular science fiction has an even shorter history, from the 1860s . </P>
