History! 1940s film explains coaxial cable, microwave networks

AT&T archive footage shows how early broadcast networks were built

The folks over at the AT&T Archives (via the AT&T Tech Channel on YouTube) have posted a "new" video from the 1940s that explained the exciting world of coaxial cables and microwave television networks to users.

What? You're not excited about this? Surely you jest.

This film, taken from a radio broadcast of the "Bell Telephone Hour", explains how the Bell System was able to construct a national broadcast network for radio syndication as well as television broadcast signals, and long-distance telephone calls. Forget about your crazy InterWeb these days - this was a techie's dream in the 1940s:

"By 1952, $40 million had been spent on the combined microwave and coaxial coast-to-coast network by the Bell System," AT&T said. The 46 cities connected via this new network were able to see the 1952 political conventions, the first to be broadcast nationwide on the new microwave network.
