The Switched at Birth summer premiere is this Monday (June 10). The one-hour cable network show has been a surprise hit for ABC Family. The stories revolve around two teenagers who were accidentally switched in the hospital and grew up with wrong family. One of the teens is deaf. ABC Family says it is "the first mainstream television series to have multiple deaf and hard-of-hearing series regulars." Some scenes are shot entirely in ASL and one recent episode was "all ASL." Here's a short video promo for the show and a video that explains the premise behind the show.
