"Recently, many instant messaging services have begun to offer video conferencing features, Voice Over IP (VoIP) and web conferencing services. Web conferencing services integrate both video conferencing and instant messaging capabilities. Some newer instant messaging companies are offering desktop sharing, IP radio, and IPTV to the voice and video features.
The term "instant messenger" is a service mark of Time Warner[2] and may not be used in software not affiliated with AOL in the United States. "
