CU-SeeMe

"When development of CU-SeeMe began in July 1992, the only real-time videoconferencing software for the Internet required expensive hardware which severely limited the number of potential senders and receivers. Working with Richard Cogger in the summer of 1992, Tim Dorcey wrote the original version of CU-SeeMe."

"Things then got off to a slow start as it wasn't until the end of July that we were even able to grab a frame from the Spigot. The first network capable version was called "WatchTim" and as near as can figure was created on August 31, 1992, except that you couldn't really watch me because I didn't have a camera. Instead you got to see a videotape of C-SPAN that I used for all of the early development. A separate application called "VideoSend" was used to transmit. (...)
[Dick Cogger] came up with "CU-SeeMe," on September 27th, I think. So, I guess that would be the official birthday for CU-SeeMe. Or, if you want to go with the first transmission outside Cornell, I would put that around September 1--shortly after the first local transmission (this is, after all, the Internet Protocol, and if you can send it across the room, you can send it around the world!)."

Timeline:
September 1992: CU-SeeMe v0.19 for Macintosh (without audio), from Cornell University.
April 1993: CU-SeeMe v0.40 for Macintosh (with multipoint conferencing)
Feburary 1994: CU-SeeMe v0.70b1 for Macintosh (with audio)
April 1994: CU-SeeMe v0.33b1 for Windows (without audio)

Note: Tim Dorcey left Cornell in 1996 to develop a next generation Internet videoconferencing system. With a small team based in Los Angeles, he released the first version of iVisit in 1997, and has been working steadily since that time to improve the state of the art in Internet communications.
