Disneys TV units are undergoing a major reorganization.

The media giant announced Tuesday that it will shutter its ABC Signature studio, combining its operations with 20th Television. Additionally, the comedy and drama development teams at Hulu and ABC are merging.

Karey Burke, president of 20th TV, will continue to lead the combined studio. Simran Sethi has been upped to president scripted programming for Hulu Originals and ABC Entertainment and will head development efforts. The reorganization will also result in about 30 layoffs, Disney says.

More to come.
