Jeff Jarvis notes that TV Guide recently sold for $1 (not per copy--for the whole thing) and says: "Beware media and news companies that try to preserve their past: This could be you."
This echos Clayton Christensen's Innovator's Dilemma. Very few companies can successfully ignore or even kill the old business to build the new one. Reading further into this story, the online piece wasn't included in the sale--Macrovision retained that part. They apparently did kill the magazine to save the future: online.
