Indeed, of last year's ten bestselling novels, five got their start as cellphone novels self-published by their authors and later picked up by a publisher and bought out as a printed book.A debut novel Love Sky by Mika was read by 20 million people on their cellphones or on websites where the novels were hosted as well. When the novel was published in book form, it became the #1 selling novel in Japan for all of last year. In addition, the novel was made into a movie. Not bad for what was essentially a self-published novel.
