Answer based on context:

Taunton has local Public, educational, and government access cable TV channels which include the Public-access television Taunton Community Access and Media, Inc. , Educational television Taunton Educational Network which is run by the Taunton High School TV Studio and Government-access television Taunton Municipal Network . Comcast's Taunton system carries all Providence and Boston stations as well and both markets are available over-the-air. The two radio stations based in Taunton are WVBF 1530 AM , which features local programming until noon followed by syndicated feed from the Reading for the Blind Network, and WSNE-FM 93.3, which primarily serves the Providence radio market and has its studios in the city of Providence. From 1949 until 2007, Taunton was also served by local radio station WPEP-AM 1570. However the station was silenced with the upgrade of Keating Wilcox's station also on 1570, in Beverly, Massachusetts. The city is now served by WVBF 1530AM Middleboro/Taunton owned by Steven J. Callahan and managed by former WPEP host, Anthony Lopes.
