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.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.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.

Many of these technologies, such as the Media space, are not as widely used today as videoconferencing but were still an important area of research.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.Simple analog videophone communication could be established as early as the invention of the television.Such an antecedent usually consisted of two closed-circuit television systems connected via coax cable or radio.An example of that was the German Reich Postzentralamt (post office) video telephone network serving Berlin and several German cities via coaxial cables between 19.
