A videophone is a telephone with a video display, capable of simultaneous video and audio for communication between people in real-time.Videoconferencing implies the use of this technology for a group or organizational meeting rather than for individuals, in a videoconference.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.During the first manned space flights, NASA used two radio-frequency (UHF or VHF) video links, one in each direction.TV channels routinely use this type of videotelephony when reporting from distant locations.
Videoconferencing has also been called "visual collaboration" and is a type of groupware.
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.
