Could the future of TV lie not in smart sets but dumb ones? Speaking at the Ad Age Digital conference today, Sony Corp. of America CFO Rob Wiesenthal makes a surprisingly admission for a TV guy. “The past 10 years everyone has been trying to figure out what is the optimum [user experience] for [internet-enabled] TV,” he said. “People are trying guns, pointer devices … and, actually, I think it is the tablet.” According to Wiesenthal, viewers increasingly will “throw” content from their tablets to their TVs using technologies similar to Apple’s AirPlay. If true, that would seem to be yet another argument against Apple making its own smart TV. Why try to compete in TVs when you already dominate the tablet market? As I’ve argued before, Apple’s best strategy for conquering the TV business could be to license AirPlay to other TV set makers and concentrate on making the iPad the primary content acquisition device. In other words, smart tablets and dumb TVs.
