A friend of mine had a mostly trad TV show for a few years on Sportsman Channel. It is SOOOO difficult to secure stable sponsors to pay for these shows.
The cost to the network is very high. This is why (and I hate em too) so many commercials are in them. Frankly, many of them look like 100% commercials. The Ozontics craze is making me sick these days.
Another thing lots of folks wouldn't know is how wishy-washy sponsors are. Would be sponsors will pleddge their support months ahead of time, expenses incurred, and then the sponsors never pay up leaving cameramen without pay, hosts going broke, etc.
The ones who make it have gimmicks that keep me from watching them. There is an especially rampant gimmick many employ these days and I switch the channel as soon as I can. They have to go overboard with the drive to market themselves.
I have found the Bob Costas treatment to be very helpful in enjoying some of these shows -- I mute the show and just watch the pictures. I don't need the nimrod telling me about the moon, fronts, Ozontics, or the latest in stink-off while I watch a deer walking through the woods.
