From the article:
"A struggling Japanese publishing industry was quick to take notice of the growing popularity of keitai shosetsu, especially early works like Yoshi's "Deep Love." Many of the popular cell phone novels have since been turned into paperbacks, and bookstores across Japan now have entire sections devoted to the digital-age literary genre.
By 2007, half of the country's 10 best-selling novels were written on cell phones, according to book distributor Tohan while last year mobile novels and comics were a $240 million market in Japan, which is over 5 percent of the country's $4.5 billion total mobile content market, according to Japan's Mobile Content Forum.
In January 2009, three Japanese mobile phone novel publishers reported collective sales of 1.7 million copies. Publishers, like Goma Books, one of the first to print cell phone novels, have also launched their own keitai shosetsu sites, which they use to sift through for talent whose work will be marketable on bookshelves."
The Japanese industry is "quick to take notice" of the changes going on around it.
The American industry is a lumbering dinosaur waiting for the meteor to strike and blot out its existence. Try more new things, American publishing!
