Animated Conan TBS Promo

This brief animated promo marking Conan O’Brien’s move to TBS this fall is a lot of fun. It’s a clear nod to Terry Gilliam and other Seventies TV show openings.

UPDATE: In the comments, Amy writes that mOcean created the Conan spot above. Also, here is another animated promo for the show:
