The creator of Switched at Birth says the show is coming to an end. Lizzy Weiss tweeted that the coming fifth season will be the last one. The Freeform network (formerly ABC Family) says the ASL-driven show will conclude with a special 90-minute finale. Switched at Birth centers on two teenage girls who discover they were swapped as newborns in a hospital mix-up. It's not a surprise that the show is ending-considering there are now 100 episodes--an important number for syndication. Also, the Freeform cable network is pulling away from family-oriented shows and rebranding itself as a network about issues facing people who've recently graduated from college--getting that first job, serious love interests, and the like. Weiss didn't say when the final season will begin.
