Films have been using books as a prime source for films for years. In 2012, six out of the nine best picture Oscar nominees were originally books. Previously, publishers did not develop their books into movie nor receive any of the profits. Neither Scholastic or Little Brown, get any box office revenue from the Harry Potter and The Twilight Saga movies just through book sales. As the publishers faced decreasing revenue due to increased competition from self-published e-books, or Amazon.com moving into the publishing field, publishers have started to enter the film and TV production business to boost their net income with Amazon attempting to compete there too. More screenwriters are turning to book publishers to get their screenplay published as a book, so as to have a boost in their attempt to have the screenplay turned into a movie, given that it is a known product after the book.
