WGBH-TV is located outside of Massachusetts.
 Three additional WGBH-owned stations were to have launched, all of which were slated to use the "WGB" prefix for their call letters; these included WGBW, which was to broadcast on channel 35 in Adams (the "W" in its callsign was to stand for "West"; the callsign has since been reassigned to a radio station in Two Rivers, Wisconsin), along with two stations in New Bedford and Worcester
WRGB claims to be the world's oldest television station, tracing its roots to an experimental station founded on 13 January 1928, broadcasting from the General Electric factory in Schenectady, NY, under the call letters W2XB
