I'm not sure where to post this so I am going with here. I don't know if anyone has ever discovered for themselves The Paley Media Center. PMC is an organization dedicated to the discussion of the cultural, creative and social significance of television. They have the best videos of the cast and crew of almost every show you can think of. There are numerous clips from the hour long dvd's that they sell on Youtube. They have annual meetings that are aired all over the world live where fans can ask questions of the cast and crew of many different shows in many different genres.
From Modern Family to Battlestar Galatica, they have a sit down with almost every genre out there. I highly recommend you check them out if you are a huge fan of TV. The link below will take you to the video page on Youtube where you can dig through, as I have, and find something on your favorite show. The Modern Family show is hilarious. I would start there if you are a fan. Enjoy!
