Microsoft introduced the NetMeeting application to allow for VoIP communications and video conferencing. NetMeeting used the H.323 protocol for video conferencing and was also compatible with OpenH323 clients like Ekiga and Internet Locator Service (ILS). It also allowed for application and desktop sharing, remote desktop sharing and transfer of files between client computers.
NetMeeting was available for use starting with later versions of Internet Explorer 3 and Windows 95 OSR2 and continued up through Windows XP. NetMeeting was one of the most popular applications for video conferencing, until free video conferencing capabilities began to be introduced in applications like Yahoo! Messenger and MSN Messenger. Microsoft changed course at this point and focused on Windows Messenger and Microsoft Office Live Meeting for its offering of video conferencing capabilities.
