Videoconferencing systems throughout the 1990s rapidly evolved from very expensive proprietary equipment, software and network requirements to a standards-based technology readily available to the general public at a reasonable cost.

Finally, in the 1990s, Internet Protocol-based videoconferencing became possible, and more efficient video compression technologies were developed, permitting desktop, or personal computer (PC)-based videoconferencing.

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.

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.

News media organizations have begun to use desktop technologies like Skype to provide higher-quality audio than the phone network, and video links at much lower cost than sending professional equipment or using a professional studio.

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.

Telepresence may refer either to a high-quality videotelephony system (where the goal is to create the illusion that remote participants are in the same room) or to meetup technology which goes beyond video into robotics (such as moving around the room or physically manipulating objects).

Videoconferencing has also been called "visual collaboration" and is a type of groupware.

At the Winter Olympics opening ceremony in Nagano, Japan, Seiji Ozawa conducted the Ode to Joy from Beethoven's Ninth Symphony simultaneously across five continents in near-real time.
