By 1947, when there were 40 million radios in the U.S., there were about 44,000 television sets (with probably 30,000 in the New York area). Regular network television broadcasts began on NBC on a three-station network linking New York with the Capital District and Philadelphia in 1944; on the DuMont Television Network in 1946 and on CBS and ABC in 1948. By 1949, the networks stretched from New York to the Mississippi River and by 1951 to the West Coast. Commercial color television broadcasts began on CBS in 1951 with a field-sequential color system that was suspended four months later for technical and economic reasons.
