Business 2.0's Erick Schonfeld has a nice take on the atomization trend in digital media. Call it microchunks, slivers, snacks. Relevance and accessibility are paramount. VC Fred Wilson articulates these principles well:
First, of course, microchunk it: Reduce entertainment to its simplest discrete form, be it a blog post, a music track, or a skit.
Second, free it: Let people download, view, read, or listen without charge. Third, share it: Let consumers subscribe to content through RSS- and podcast-style feeds so they can enjoy it wherever and whenever they like. Finally, the moneymaking part: Put ads and tracking systems into the digital content itself.
