Momma's Boy is another one I don't watch, but I think you're right about it being NBC. There were several episode of it on BRAVO tonight. NBC and BRAVO are sister networks, but isn't this show brand new? I don't understand the repeating so soon, even if today is a holiday.
I also think you are right about reality shows being a result of the Writer's strike, but the strike of many years ago - back when Survivor started. The most recent strike just added to the numbers. I don't know where all the writers went after the strike, but I don't think they returned to TV.
I'm sure I don't know the criteria for being called "reality". I mentioned Jay's new project above; it is planned to be a primetime talk show. Rosie just started a primetime variety show. I don't know if that is making it, or even still one. Are either of them called "reality"?
