I have now read Wikipedia's entry for The DuMont Network, and I discovered that it was a poor 4th network, because it was the only one that didn't have the support of large revenues from its own radio network; and it only owned 3 stations, and only the one in Pittsburgh was VHF, The others were UHF, which had no channels built onto the TVs. They did partner with WGN (Channel 9 in Chicago), to get much of their programming on the air there. And upon seeing the DuMont logo, I remember it, now. But, they were gone before the end of 1956, and well before we moved from Canada to Chicago. I learned That The Mutual Broadcasting System applied to get a TV broadcasting license, but The FCC declined, not wanting to add more systems. ABC partnered with Paramount, to be able to compete with NBC and CBS, and DuMont was forced out. I hadn't known that Jackie Gleason had had a variety show on The DuMont Network, which had "The Honeymooners" first as a weekly sketch, and that the first 39 episodes of the TV show, aired on DuMont or affiliated private stations (WGN being one of them).
