1930 Bell Telephone Laboratories conducted experiments with "Two-way Television" culminating with a demonstration on April 9, 1930. A "phone call" was held between the 195 Broadway headquarters and the BTL facility at 463 West Street in New York City, as representatives of the press looked on. Signals were sent over normal phone wiring, suggesting that distance was not a limiting factor. It was noted that while interesting, commercial prospects were "uncertain." Behind each booth was a room full of complex electrical and mechanical equipment, including water cooled neon receiving tubes, rotating scanning disks and racks of gear. The bandwidth required for thousands of stations was well beyond the capacity of existing exchanges. Click here for more details. (Photo from The Northwestern Bell, May 1930.) |
