The content for this 1946 film was taken from a radio broadcast of the Bell Telephone Hour.
This film provides a short explanation of how the national broadcast network formed a backbone built by the Bell System to not only handle radio syndication, but also television broadcast signals, and long-distance telephone calls. The network was made up of a series of line-of-sight microwave towers combined with coaxial cable. The film explains the new technologies that reduced the size and number of wires and cables, replacing them with microwave systems and relays.
By 1947, the Bell System's microwave broadcast corridor handled television signals between New York and Boston. Western Union had a competing microwave line between Pittsburgh and Washington D.C.; General Electric transmitted between New York City and Schenectady; and Philco broadcast along the New York City to Philadelphia corridor. But while these other companies carried television signals, the Bell network carried both television and telephone signals. Even something called "radio mail" was proposed--a high-speed fax service for missives and photos to be transmitted via the microwave network.
By 1952, $40 million had been spent on the combined microwave and coaxial coast-to-coast network by the Bell System, which employed 107 towers coast-to-coast to carry telephone and television signals. The 1952 political conventions were the first to be broadcast nationwide, using this network, which included 46 cities.
