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.Very expensive videoconferencing systems rapidly evolved throughout the 1980s and 1990s from proprietary equipment, software and network requirements to standards-based technologies that were available for anyone to purchase at a reasonable cost.Only in the late 20th century with the advent of powerful video codecs combined with high-speed Internet broadband and ISDN service did videotelephony become a practical technology for regular use.

In 1984, Concept Communication in the United States replaced the then-100 pound, US0,000 computers necessary for teleconferencing, with a ,000 circuit board that doubled the video frame rate from 15 up to 30 frames per second, and which reduced the equipment to the size of a circuit board fitting into standard personal computers.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.The first dedicated systems started to appear as ISDN networks were expanding throughout the world.More popular videotelephony technologies use the Internet rather than the traditional landline phone network, even accounting for modern digital packetized phone network protocols, and even though videotelephony software commonly runs on smartphones.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.
