The term "webinar" is a portmanteau of web and seminar, meaning a presentation, lecture, or workshop that is transmitted over the web. The coined term has been attacked for improper construction, since "inar" is not a valid root. Webinar was included on the Lake Superior University 2008 List of Banished Words, but was included in the Merriam-Webster dictionary that same year.
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.”
Web conferencing technologies are not standardized, which has reduced interoperability and transparency and increased platform dependence, security issues, cost and market segmentation. In 2003, the IETF established a working group to establish a standard for web conferencing, called "Centralized Conferencing (xcon)". The planned deliverables of xcon include:
"I invested $10,000 to learn similar content from another well-known industry leader a few years ago. I left Tamara's two-hour online workshop even better equipped and ready to take action to step up my game of leading successful webinars. Being able to learn the content and how-to information by webinar without having to drive or fly anywhere is a huge value. And I invested about $9500 less to boot! I highly recommend this training."
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." 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 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.
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.
