Unveiled in 1996 by InSoft Inc., CoolTalk was a multimedia software tool that let PC users view data displayed on a shared whiteboard, exchange real-time messages via a chat tool or speak with each other via a TCP/IP voice connection. The product worked with Microsoft Sound System-compatible audio boards and was available in a 14.4-kbit/s version or 28.8-kbit/s version. CoolTalk was later packaged with popular Web browsers of the time.[20] CoolTalk 14.4 and 28.8 sold for $49.95 and $69.95, respectively, in 1996.[11][21]

In April 1999, Vstream introduced the Netcall product for web conferencing as "a fee-based Internet software utility that lets you send business presentations and other graphic information via e-mail to a Vstream server. Vstream converts the content, again using streaming technology, and makes the presentation available for viewing by up to 1,200 people at a time."[28] Vstream changed the company name to Evoke Communications in 2000, with a further change to Raindance Communications in 2002. In February 2006, Raindance was acquired by the InterCall division of West Corporation.
