David Pogue wrote a good “Where’s HDTV?” interview with Gary Merson (senior video editor for The Perfect Vision magazine, and author and publisher of the HDTV Insider newsletter) for the New York Times.
The three major networks are broadcasting the vast majority of their prime time shows in HDTV. This week, for example, CBS will broadcast 19 of its 22 prime-time hours in HDTV. The networks have announced that David Letterman and Conan O’Brien’s shows will join Jay Leno in HDTV. Major sporting events and programs will also be in HDTV, including The Academy Awards, The Grammys, US Open Tennis, Basketball, Monday Night Football, and many more. Even the WB is offering shows in HD.
Also currently in HD almost 24 hours a day: HBO, Discovery HD Theater, HD Net and Showtime. (You can get these either by satellite or, within several months, cable.) Additional HD channels coming on board this year: Cinemax, ESPN, three more HD Net Channels (movies, sports, entertainment), The Hallmark Channel and Bravo HD.
