The development of the crucial video technology first started in the latter half of the 1920s in the United Kingdom and the United States, spurred notably by John Logie Baird and AT&T's Bell Labs.

This occurred in part, at least with AT&T, to serve as an adjunct supplementing the use of the telephone.

One of the first commercial videoconferencing systems sold to companies came from Picture Tel Corp., which had an Initial Public Offering in November, 1984.By reducing the need to travel to bring people together, this technology also contributes to reductions in carbon emissions, thereby helping to reduce global warming.The concept of videotelephony was first popularized in the late 1870s in both the United States and Europe, although the basic sciences to permit its very earliest trials would take nearly a half century to be discovered.The news media were to become regular users of mobile links to satellites using specially equipped trucks, and much later via special satellite videophones in a briefcase.This technique was very expensive, though, and could not be used for applications such as telemedicine, distance education, and business meetings.This was first embodied in the device which came to be known as the video telephone, or videophone, and it evolved from intensive research and experimentation in several telecommunication fields, notably electrical telegraphy, telephony, radio, and television.
