Specifically, Brigham Young University is producing a show featuring everyday citizens and their quests to learn more about their ancestors. It's titled "The Generations Project".
If you don't get BYU TV - and I imagine most of us don't - you can watch the most recent episode online on their website here.
I am halfway through the most recent episode and really like it. I feel like it goes more in-depth on a single individual or branch of the tree than the other two programs. I also appreciate hearing about the history of "ordinary" people's families. It's a different take than the celebrity route. Though of course I think that everyone's family history is really equally interesting!
