How does one get a direct user support show off the ground though? Are sufficient numbers of people going to be willing to pay $1 an episode for a show they've never seen? I doubt it. Maybe it would work if you gave away the first few episodes for free, and then you start charging, but if you give it away for free how do you afford to produce it? The answer to that last question is, advertising.
Personally I very rarely actually watch adverts on live broadcast TV. I tend to use the time to do quick miscellaneous household chores like running the vacuum clear round or washing up. So to me the time the adverts are on doesn't cost me anything because I make productive use of the time. I live in the UK though where we never get more than 3 breaks in an hour long show or 1 break in a half hour show. So the breaks tend to run 4-5 minutes. From what I've heard of US TV I believe you tend to get a larger number breaks of shorter duration and that time would be harder to make use of in the way I do.
