Book publisher, Penguin, is setting its sights on the digital-only market with their new Penguin Shorts programme. The premise of the move is to focus on short reads that'll be available for $1.99 USD a pop and fertilize its own niche among avid digital readers. Not a bad idea considering music went the route of singles and the iTunes store. And with gadgets like the Kindle Fire and Nook, who's to say the reading market won't adapt just as easily as music has? Smart.
