As you may now know, analog broadcast TV as we know it is about to be scrapped in the US. I forgot the exact date, but IIRC by late 2008, the analog broadcast spactrum will be revoked by the FCC.
Title III--Digital Television Transition and Public Safety Act - setting a firm date of February 17, 2009 for the cessation of Analog broadcasts. Supposedly there will be a digital broadcast TV replacing it in many markets, but at the very least you'll need either an expensive set-top convert box, or a new digital TV.
Most markets are already broadcasting in digital alongside the analog. It is hard to find converters for under $200. As with many of the other digital rights management 'solutions', the general public is generally blissfully unaware of what's currently looming over the horizon, and will remain so until it's too late.
We collect old time radio shows in mp3 format and listen to those instead of watching tv. More quality and more entertaining than anything on TV.
