In 1992 CU-See Me was developed at Cornell by Tim Dorcey et al.
In 1995 the first public videoconference between North America and Africa took place, linking a technofair in San Francisco with a techno-rave and cyberdeli in Cape Town.
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.
While videoconferencing technology was initially used primarily within internal corporate communication networks, one of the first community service usages of the technology started in 1992 through a unique partnership with Picture Tel and IBM Corporations which at the time were promoting a jointly developed desktop based videoconferencing product known as the PCS/1.
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.
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.
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.A videophone is a telephone with a video display, capable of simultaneous video and audio for communication between people in real-time.
