PBS: Don't overlook it for HDTV
HDTV programming is still relatively scarce via over-the-air broadcasting. Most of the major neworks have some prime-time programs in high-definition and you can usually rustle up a sporting event or two on the weekend. Here's a thought the next time you've got to have your HDTV: check out your local Public Broadcast System (PBS) channels.
PBS offers HDTV at various times throughout the day, not just during prime-time. Just to give you an example, I checked my local PBS station guide for high-def. From midnight this morning to midnight tonight, my local PBS channels are offering fifteen hours of HD programming. Granted, some of these are rebroadcasts, but there's plenty to watch ranging from local news, shows on the arts, and travel programs.
