WPEC is the CBS-affiliated television station for the Gold and Treasure Coasts of South Florida. Licensed to West Palm Beach, it broadcasts a high definition digital signal on VHF channel 13 from a transmitter southeast of Wellington along U.S. 441/SR 7, in unincorporated Palm Beach County. Owned by the Sinclair Broadcast Group, the station is sister to The CW affiliate WTVX, Class A MyNetworkTV affiliate WTCN-CA and Class A Azteca América affiliate WWHB-CA. All of the television outlets share studios together on Fairfield Drive in Mangonia Park (with a West Palm Beach postal address).
The station signed-on as an ABC affiliate with the call letters WEAT-TV on January 1, 1955. It was owned by RKO General. Its original studios were on South Congress Avenue in West Palm Beach. RKO sold the station to Rex Rand in 1957. In 1964, Gardens Broadcasting, a company founded by businessman John D. MacArthur bought the station. In 1973, Photo Electronics bought the station from John D. MacArthur. The station moved to its present studio facilities on Fairfield Drive in Mangonia Park that same year. On January 27, 1974, the WEAT calls were changed to the current WPEC which stood for Photo Electronics Corporation in reference to the station's then-current owner, a company founded by local entrepreneur Alexander W. Dreyfoos, Jr.. The previous calls are currently used by an area radio station that is owned by Palm Beach Broadcasting.
