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]
A good webinar software should be selelcted during the preparation. But how to choose the right one and how to do a webinar for free ?

Depending on the technology being used, participants may speak and listen to audio over standard telephone lines or via computer microphones and speakers. Some products allow for use of a webcam to display participants, while others may require their own proprietary encoding or externally provided encoding of a video feed (for example, from a professional video camera connected via an IEEE 1394 interface) that is displayed in the session.

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.”
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.
In 1996, PlaceWare was founded as a spinoff from Xerox PARC. In November of that year, PlaceWare Auditorium was described in a public talk at Stanford University as allowing "one or more people to give an interactive, online, multimedia presentation via the Web to hundreds or thousands of simultaneous attendees; the presentation can include slides (made in PowerPoint or any GIF-image editor), live annotation on the slide images, real-time polls of the audience, live audio from the presenter and those asking questions, private text and audio conversations in the auditorium's "rows", and other features."[18] PlaceWare Auditorium was formally announced in March 1997 at a price of $150 per simultaneous user.[19]
Using Webinar software participants can share audio, documents and applications with webinar attendees. This is useful when the webinar host is conducting a lecture or information session. While the presenter is speaking they can share desktop applications and documents. Today, many webinar services offer live streaming options or the ability to record your webinar and publish to YouTube and other service later.
