DuMont did not have a radio network like ABC or CBS. During all this, the Mutual Broadcasting System had considered creating a TV network. They would have Metro-Goldwyn-Mayer make some of the programming. WOR-TV &amp; WOIC were known as "Mutual Television." This is the only evidence of the television network. Mutual then bought a stake in the Overmyer Network in 1967. That network never succeeded.
