WWTV (channel 9) is a television station licensed to Cadillac, Michigan, United States, serving as the CBS affiliate for the northern Lower and eastern Upper peninsulas of Michigan. It is owned by locally based Heritage Broadcasting Group, which provides certain services to Cadillac-licensed dual Fox/CW+ affiliate WFQX-TV, channel 32 (and its Vanderbilt-licensed full-time satellite, WFUP, channel 45) under a shared services agreement (SSA) with Cadillac Telecasting. Both stations share studios on Broadcast Way (near US 131) in Cadillac, while WWTV's transmitter is located on 130th Avenue in unincorporated Osceola County, just northeast of Tustin. Like other network affiliates serving this vast and mainly rural area, WWTV operates a full-time, full-power satellite in Sault Ste. Marie, WWUP-TV (channel 10), whose transmitter is located approximately south-southeast of Sault Ste. Marie near Goetzville in southeastern Chippewa County (on a tower shared with ABC affiliate WGTQ). Aside from its transmitter, WWUP does not maintain any physical presence in Sault Ste. Marie, Michigan. Together, the two stations are known on-air as 9&10 and serve the largest television market east of the Mississippi River: 23 counties in the northern Lower Peninsula and three counties in the eastern Upper Peninsula. In addition, WWUP's signal can be received by viewers in Northern Ontario including Sault Ste. Marie's Canadian sister city. History Sparton Corporation, a Jackson-based radio manufacturer, won the license for channel 13 in June 1953 was assigned the call letters WWTV. In November 1953, Sparton sent advertising agents and "queens" to New York to drum up advertising by tell the "Northern Michigan Story" with programming expected to start on December 15. Delays pushed back the on-air date to January 1954, though it began airing regular test patterns on December 13, 1953. WWTV began broadcasting on New Year's Day in 1954. It was Michigan's first television station north of Lansing, predating Traverse City's WPBN-TV (channel 7) by several months. WWTV has been a CBS affiliate from its first day, but initially carried secondary affiliations with ABC and DuMont (the latter shut down in 1956). When WPBN signed on, WWTV shared ABC programming with that station until 1971, when WGTU (channel 29) signed on and became the area's ABC affiliate. WWTV aired some of ABC's soap operas and game shows while WPBN aired ABC's sports programming on the weekends. In 1958, broadcast pioneer John Fetzer purchased WWTV. Fetzer also owned the Detroit Tigers, and the purchase brought Tigers games
