This is one of the better "reality-based" shows on network TV since it has to do with learning about yourself and where you originally came from, but not the best.
Since celebrities are used in each episode, this show needs more diverse people to discuss their genealogy with. There are approximately 10 episodes per season and out of all of the episodes, only ONE person depicted is non-white. We live in a melting pot of ethnicities, and there are hundreds of actors that are non-white that have fascinating genealogy stores to be told.
"Finding Your Roots" on PBS is MUCH more diverse in who's history to follow whether they are black, hispanic, Jewish, or homoesexual. Check your local PBS stations of when it will air. Generally "Finding Your Roots" starts airing in Sept. It's more worthwhile to watch.
