The Overmyer Network/United Network was a short-lived television network. It was intended to be a fourth national commercial network in the United States, competing with the Big Three television networks. The network was founded by self-made millionaire Daniel H. Overmyer, who built five UHF stations from 1965 to 1967 (including Toledo's WDHO-TV (now WNWO-TV, an NBC affiliate), which signed on the air on May 3, 1966). A social conservative ("I'm against smut," he declared), Overmyer began to produce his own programs, and decided to create a nationwide hookup, enticing existing stations with a 50-50 profit split with potential affiliates (something that the established network's affiliates had been trying to get from ABC, CBS and NBC for years). Under the leadership of former ABC television president Oliver Treyz, the ON was scheduled to debut in the fall of 1967 with anywhere from 75 to 125 affiliates with an 8 hour broadcasting day.
The network planned to offer eight hours of programming per day, seven days per week, to its affiliate stations. A daily news service, from United Press International, would provide each station with news. Cultural and sports programming, including Tales from the Great Book (an animated Bible series) and regional games of the Continental Football League, were also planned. By July 1966, 35 stations had agreed to affiliate with the new network.
