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]
If there is a bunch of additional learning resources to be referred to during the webinar and have been prepared in advance, there will be a need to host them somewhere. You will need to set up a link of associating with the learning material inside the webinar. Some of the participants will definitely spend some money on it as they are eager to get more relative knowledge. You might also be charged for hosting the webinar and this will be part of your budget if you intend on gaining some profit with the webinar. But you're also getting money from effective broadcasting as it plays an advertising role. In other words, you're creating webinars for profit.
Web conferencing software is invoked by all participants in a web meeting. Some technologies include software and functionality that differs for presenters and attendees. Software may run as a web browser application (often relying on Adobe Flash, Java, or WebRTC to provide the operational platform). Other web conferencing technologies require download and installation of software on each participant's computer, which is invoked as a local application. Many web conferencing vendors provide the central connectivity and provisioning of meeting "ports" or "seats" as a hosted web service, while others allow the web conference host to install and run the software on its own local servers. Another installation option from certain vendors allows for use of a proprietary computer appliance that is installed at the hosting company's physical location.
Let’s face it. Your audience has been conditioned to think “show me the money” by all the scams, gimmicks and otherwise sketchy products out there (and if not that, through Jerry McGuire movie quips for sure). If attendees still haven’t purchased anything several days after your webinar, they are probably thinking, “Your product sounds great, but show me real results from real people like me.”
Presentation of visual materials most often is accomplished through one of two primary methodologies. The web conferencing software may show participants an image of the presenter's computer screen (or desktop). Again, depending upon the product, the software may show the entire visible desktop area or may allow selection of a physical area or application running on the presenter's computer. The second method relies on an upload and conversion process (most commonly consisting of Microsoft PowerPoint files, other Microsoft Office electronic documents, or Adobe PDF documents).
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.

Web conferencing may be used as an umbrella term for various types of online collaborative services including web seminars ("webinars"), webcasts, and peer-level web meetings. It may also be used in a more narrow sense to refer only to the peer-level web meeting context, in an attempt to disambiguate it from the other types of collaborative sessions.[1] Terminology related to these technologies is inexact, and no generally agreed upon source or standards organization exists to provide an established usage reference.
