"WETA-TV is a Public Broadcasting Service television station for the Washington, D.C. area. Its studios are in nearby Arlington, Virginia. Among WETA's nationally-broadcast programs are PBS Newshour and Washington Week and several nationally-broadcast cultural and documentary programs, such as the Ken Burns' documentaries and A Capitol Fourth."

In 2002, WETA became one of the first stations to offer digital subchannels, which initially included WETA Prime, WETA Plus, and WETA Kids. In January 2006, WETA changed subchannels lineup with WETA Create, WETA Family, and WETA World, after the closure of national services PBS You and PBS Kids.
