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.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.A number of organizations believed that videotelephony would be superior to plain voice communications.

Videoconferencing implies the use of this technology for a group or organizational meeting rather than for individuals, in a videoconference.Attempts at using normal telephony networks to transmit slow-scan video, such as the first systems developed by AT&T Corporation, first researched in the 1950s, failed mostly due to the poor picture quality and the lack of efficient video compression techniques.The greater 1 MHz bandwidth and 6 Mbit/s bit rate of the AT&T Picturephone in the 1970s also did not achieve commercial success, mostly due to its high cost, but also due to a lack of network effect — with only a few hundred Picturephones in the world, users had extremely few contacts they could actually call to, and interoperability with other videophone systems would not exist for decades.At the dawn of its commercial deployment from the 1950s through the 1990s, videotelephony also included "image phones" which would exchange still images between units every few seconds over conventional POTS-type telephone lines, essentially the same as slow scan TV systems.The development of advanced video codecs, more powerful CPUs, and high-bandwidth Internet telecommunication services in the late 1990s allowed videophones to provide high quality low-cost colour service between users almost anyplace in the world that the Internet is available.
