"The Jurassic Park franchise is a series of books, films, comics, and videos centering on a disastrous attempt to create a theme park of cloned dinosaurs. It began in 1990 when Universal Studios bought the rights to the novel by Michael Crichton before it was even published.
The book was successful, as was the 1993 film adaptation which led to two sequels, although the last was not based on a novel, as the previous films were. The software developers Ocean Software, BlueSky Software, Sega of America and Telltale Games have had the rights to developing video games since the 1993 film, and numerous games have been produced."
