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. CoolTalk 14.4 and 28.8 sold for $49.95 and $69.95, respectively, in 1996.
In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations from a web-connected computer to other web-connected computers.
For example, if you’re hosting a webinar on how to use WordPress blogs, and participants are asking a lot about increasing traffic, you could position your email like this: “I’m getting a lot of questions about boosting traffic to your blogs, so I’m throwing in a bonus how-to guide which will be sold later for $97, but you’ll get it free if you act now.”
A webinar is a live, web-based video conference that uses the internet to connect the individual (or multiple individuals) hosting the webinar to an audience of viewers and listeners from all over the world. Hosts can show themselves speaking, switch to their computer screens for slideshows or demonstrations, and even invite guests from other locations to co-host the webinar with them.
