First edition of the technical description of Bell System's picturephone System.

When the system was launched it was regarded as a state of the art information tool. It was being used in various science fiction-movies, among these, Stanley Cubric's A Space Odyssey.
"The AT&T picturephone offered full motion, a monochrome picture, and about half the resolution of a conventional TV image. It worked over three phone lines, and though fairly costly, was somewhat affordable. The AT&T picturephone utilized sophisticated image technology and was a well designed product offering desk-top, impulse use." (Noll, Michael. Highway of dreams: a critical view along the information superhighway, 1997, p. 27).

It never became a huge success and after a few years only, it was taken off the market. In the history of the telephone and communication in general, however, it occupies an important role, as this was the first time that a visual personal communication tool was being offered to a broad audience. In this respect, it can be regarded as the forerunner of web-cam and video mobiles.
