Despite its simple narrative style, Robinson Crusoe was well received in the literary world and is often credited as marking the beginning of realistic fiction as a literary genre. It is generally seen as a contender for the first English novel. Before the end of 1719, the book had already run through four editions, and it has gone on to become one of the most widely published books in history, spawning so many imitations, not only in literature but also in film, television, and radio, that its name is used to define a genre, the Robinsonade.
