Dan Frommer lays out the myriad obstacles to the “Apps As TV Channels” model everyone is talking about. Bottom line:
The people running TV networks are not dummies. They may be slow to adopt new technology, but they’re not stupid. They saw what “working with Apple” did to the music industry. And they are set on making sure that if Internet distribution and new technologies eventually redraw the entire TV distribution chain, it happens on their terms and on their schedule.
Basically: It’s all about preserving their existing business models.
