First IETF internet audiocast
Stephen L. Casner, S. Deering · ACM SIGCOMM Computer Communication Review · 1992
At the March, 1992 meeting of the Internet Engineering Task Force (IETF) in San Diego, live audio from several sessions of the meeting was “audiocast” using multicast packet transmission from the IETF site over the Internet to participants at 20 sites on three continents spanning 16 time zones. This experiment was not only the first sizeable audio multicast over a packet network, but also significant for the size of the IP multicast network topology itself.
