When i tell people that i teach television, they sometimes boast, "I don't even own a TV set!" All I can say is that we inhabit different realities.

I read Phillip Swann's TV dot Com: The Future of Interactive Television with the same sense of looking across a vast cultural divide. Swann, the former publisher of TV Online magazine, thinks interactive television should and will be designed  for channel zappers: "Few viewers today can sit through an entire program without picking up the remote and checking out another channel."

In Swann's future, variety and magazine shows will almost entirely displace dramas, and the few remaining series will be shrunk to 30 minutes or less, reflecting dwindling attention spans. VCRs will be "shelved forever" once the hard drives for personal videorecorders "expand to permit consumers to store dozens of hours of programming." Swann devotes an entire chapter to the silly idea that viewers will want to disrupt the flow of Ally McBeal in order to buy, right then and there, whatever Ally happens to be wearing.

I wish I could dismiss Swann as an eccentric, but similarly bad ideas are circulating in Hollywood too. The future of interactive television is being designed by and for people who don't care for television. One researcher brags he can compress any show into half its original length. In his perfect world, television might consist of nothing but coming attractions. According to Swann, "People will start watching TV shows the way they read books: a little at a time." Such plans reflect an impoverished understanding of television viewing and a lack of interest in the medium's aesthetics.
