I've been amazed in the past few weeks at how many people don't know that OTA TV exists. They know about cable and satellite TV, and now are hearing about TV via the internet, but a friend did a survey here locally in San Francisco and a large number of people didn't know that you could connect an antenna to your TV set and get beautiful HD pictures. (What did they think that tall Sutro Tower was used for?) I think it's time for TV stations to publicize the fact that you can get free TV really easy by simply buying an antenna... or would that upset the cable and satellite operators too much? Are people in other parts of the country similarly unaware of OTA TV?
