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 1965-67 (including Toledo's WDHO-TV (now WNWO-TV, an NBC affiliate), which signed on the air on May 3, 1966).
