One of the early collaboration and conferencing programs introduced in 1996 by Microsoft and retired in late 2003 by the company. NetMeeting was bundled as part of Windows and included point-to-point telephony and videophone capability over the Internet as well as multipoint whiteboard and application sharing.

The advent of instant messaging (IM) and other alternatives for online, real-time communication contributed to its demise. Microsoft announced a replacement online meeting service called Office Live Meeting, formerly from PlaceWare, a company Microsoft acquired in 2003. See ULS server.
