Picturephone !

Posted: August 21, 2011 in Technology



The first Picturephone test system, built in 1956, was crude – it transmitted an image only once every two seconds. But by 1964 a complete experimental system, the “Mod 1,” had been developed. To test it, the public was invited to place calls between special exhibits at Disneyland and the New York World’s Fair. In both locations, visitors were carefully interviewed afterward by a market research agency.

People, it turned out, didn’t like Picturephone. The equipment was too bulky, the controls too unfriendly, and the picture too small. But the Bell System was convinced that Picturephone was viable. Trials went on for six more years. In 1970, commercial Picturephone service debuted in downtown Pittsburgh and AT&T executives confidently predicted that a million Picturephone sets would be in use by 1980.

What happened? Despite its improvements, Picturephone was still big, expensive, and uncomfortably intrusive. It was only two decades later, with improvements in speed, resolution, miniaturization, and the incorporation of Picturephone into another piece of desktop equipment, the computer, that the promise of a personal video communication system was realized.
