 Unfortunately, you can't see HGTV's higher quality on regular TV. And for now, HGTV does suffer from high prices and scarce programming. But there's little doubt that television signals are going digital. I think that the world of television for entertainment is poised for explosion. And that explosion comes about because television becomes digital. Andy Lipman is associate director of MIT's Media Lab, one of the premier technology think tanks in the world. The lab is supported by more than 170 corporate sponsors, ranging from toy maker Mattel to chip maker Intel. All agree to share the R&D costs and the discoveries made at the lab. Those discoveries can range from creating animated creatures that think for themselves to sneakers that play music as you move in them. From his perch at the lab, Lipman sees a digital explosion. And when television becomes digital, it becomes a lot more like the internet. And that means that instead of 100 or 500 or 1000 channels, you have to think of television in terms of 243 million channels and accessing channels from all around the world.
