KPHO-TV (channel 5) is a television station in Phoenix, Arizona, United States, affiliated with CBS. It is owned by Gray Television alongside independent station KTVK (channel 3) and low-power LATV affiliate KPHE-LD (channel 44). KPHO-TV and KTVK share studios on North Seventh Avenue in Uptown Phoenix; KPHO-TV's transmitter is located on South Mountain on the city's south side. Arizona's first television station, KPHO-TV operated as an independent station for nearly 40 years, during which time it sometimes measured as the most-watched independent within its market in the United States; one of its productions, The Wallace and Ladmo Show, was among the longest-running local children's programs in the country. It switched to CBS in 1994 as the result of a group affiliation deal between the network and the Meredith Corporation, which owned the station for nearly 70 years. The CBS affiliation also led the expansion of what had been a small news department into one broadcasting dozens of hours of local news a week. History Early history On March 4, 1948, a consortium of four men doing business as the Phoenix Television Company—R. L. Wheelock, W. L. Pickens, H. H. Coffield, and John B. Mills—filed an application with the Federal Communications Commission for a construction permit to build a new television station on channel 5, which was granted on June 2. This was the first application—and permit—for a television station in Arizona. The venture united Mills, the owner of downtown Phoenix's Westward Ho hotel, with three Texas oilmen. By the time it incorporated with the state in June 1949, Phoenix Television, Inc. had gained several new shareholders, notably including John Mullins, who later owned other radio and television properties. Another was Rex Schepp, the owner and manager of KPHO (then at 1230 AM; it moved to 910 kHz in 1949), which was Phoenix's ABC radio outlet; Mills then bought a 29 percent interest in KPHO. By summer, construction had begun on a building adjacent to the Westward Ho, at 631 N. First Avenue, to house offices and studios for the station, which initially had the call letters KTLX. Phoenix Television also began work on a steel mast to be affixed to the structure for its antenna. The KTLX call sign was dropped on October 4 in favor of KPHO-TV, to match the radio station. Arizona's first television station began broadcasting on December 4, 1949; network coaxial cables had not reached Phoenix,
