Digital Television! A few years ago, America made the big push into Digital TV. Suddenly, everyone had to buy a new antenna. The Federal government even offered coupons to help folks afford the new technology. Many networks, and even smaller, local TV stations, began offering additional channels to viewers. As with everything these days, its all about content and having something to build around advertising. Take, for example, the Decades Channel. Part of the CBS network, this channel is dedicated to focusing on one decade, or sometimes even just one year, of the past. One-time news reader, Bill Curtis, hosts the channel. Programming during the week usually includes a historical look at the decade or year, plus one movie and several TV series episodes from that era. This weekend, the Decades Channel took us back to the Age of Polyester, the 1970s, with a weekend-long marathon of ″Celebrity Bowling″.
