TV channels routinely use this type of videotelephony when reporting from distant locations.

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.

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.

Videotelephony developed in parallel with conventional voice telephone systems from the mid-to-late 20th century.

One of the first commercial videoconferencing systems sold to companies came from Picture Tel Corp., which had an Initial Public Offering in November, 1984.

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.

In the 1980s, digital telephony transmission networks became possible, such as with ISDN networks, assuring a minimum bit rate (usually 128 kilobits/s) for compressed video and audio transmission.

During this time, there was also research into other forms of digital video and audio communication.

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