Dumont's problem was much more than New York- it was all over the country- he just didn't have enough affiliates- and there wasn't enough stations on the air in the early '50s to support 4 networks. Even ABC was barely surviving in those days. What's more, TV distribution had to be done by microwave or coax then which was VERY expensive. Only the most successful networks could afford it. Now a day's it's done by satellite which is cheap by comparison. In fact, there are many small networks now- especially sports networks that are successful now because there are more stations and cheaper distribution. Dumont was just ahead of his time.
