WWHB-CD

WWHB began broadcasting on January 11, 1991, as an independent station with the call sign W16AR. It was located on UHF channel 16 and was licensed to Stuart.^[2] Retired businessman August Gabriel began the station with $200,000 and three employees.^[3][4] It changed its call sign to WTCN-LP in 1995. From October 1996 until February 1997, it briefly produced a local morning show known as Good Morning Treasure Coast that was hosted by Tom Teter. Ed Birchfield also briefly hosted a 7 p.m. Treasure Coast News program from February to July 1997.^[5][6]

The station moved to UHF channel 15 in 2001 (when it converted to Class A and changed its calls to WTCN-CA in February of that year) and then to UHF channel 14 in 2002.^[7] It added a translator on UHF channel 53 in order to reach West Palm Beach.^[8] On January 15, 2003, the station changed its calls to the current WWHB-CA and switched to UHF channel 48. This aired from a transmitter at the western boundary of Johnathan Dickinson State Park in Martin County southwest of Jupiter Island.

Martin County businessman Bill Brothers purchased the station in 2001. It was Brothers who revitalized the station creating the first Hispanic language local television service for the West Palm Beach market. Rebuilding the broadcasting facilities together with his sister station WTCN, WWHB served the Treasure Coast's rapidly growing Hispanic population.^[9] In 2005, Viacom bought WWHB and sister station WTCN (channel 43) from Brothers for $7.7 million.^[10] Viacom moved the studios back to West Palm Beach and improved the station's signal.^[11]

On February 7, 2007, CBS agreed to sell seven of its smaller-market stations to Cerberus Capital Management, L.P., for $185 million.^[12] Cerberus then formed a new holding company for the stations, Four Points Media Group, which took over the operation of the stations through local marketing agreements in late-June 2007.^[13] The deal closed on January 10, 2008. Although the URL for the WWHB website has not changed since the sale to Four Points, it now redirects to a separate section of WTVX's website. As of February 25, 2008, the station is now being operated out of Four Points' hub station KUTV in Salt Lake City, Utah.

On September 8, 2011, Sinclair Broadcast Group announced its intent to purchase Four Points from Cerberus Capital Management for $200 million; Sinclair began managing the stations, including WWHB-CA, under local marketing agreements following antitrust approval.^[14] The deal with Sinclair acquiring Four Points was completed on January 3, 2012.^[15]

On January 1, 2023, WWHB-CD switched to TBD programming after Azteca América ceased operations, sharing the affiliation with WTCN-CD's third digital subchannel.
