The CrunchPad may be dead, but interest in getting rich news content onto new types of devices remains very much alive. Today, Hearst unveiled Skiff, a new service to sell digital versions of magazines and newspapers to electronic readers and other devices. Unlike Amazon’s Kindle store, Skiff editions will carry graphics and advertising. Hearst is also an investor in First Paper, which is developing its own e-reader, and today’s Skiff announcement could be a prelude to a reader launch. Earlier this week, Time Inc., unveiled a concept demo for a tablet version of Sports Illustrated. Too bad Apple’s iPad tablet remains a rumor.
