Microsoft is retiring its six-year-old NetMeeting online conferencing application and instead will push Office Live Meeting, formerly known as PlaceWare, for online meetings, as reported by Infoworld. NetMeeting helped pioneer online conferencing when it was released in May 1996, before the advent of instant messaging (IM) and other services for real-time online communication. The software still ships as part of Windows and some of its features, such as whiteboarding and application-sharing, are used by the MSN Messenger and Windows Messenger IM applications. But NetMeeting has served its purpose and will gradually be phased out, Microsoft spokeswoman Stacy Drake said. Microsoft has already stopped development work on NetMeeting and links from MSN Messenger and Windows Messenger will be cut in future updates to those products, she said.
