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." PlaceWare Auditorium was formally announced in March 1997 at a price of $150 per simultaneous user.
Webinars are a form of online education whose purpose is to pass skills or knowledge across to those who want to learn. They are very useful and highly detailed in their nature and if they are explaining a concept, nothing will be left out of the explanations. Webinars are important in the modern world where putting together pieces of information in order to muster a skill or some knowledge becomes very hard and involving. However, the use of a webinar cuts down the costs and brings lots of benefits, even including making money with webinars.
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.
