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.
Don’t feel you need to do a weekly series. A monthly series works just fine, though twice a month is a nice middle ground. And if your schedule is too busy (and let’s be honest, of course it is…), then use a webinar platform like EverWebinar to host an automated webinar. You won’t even need to be there. Heck, you could be kicking it in Belize with a Pina Colada, watching the sales roll in while your webinar is running without you.
To attract more participants, you can start from some free webinars for certain times. Once you can get webinars well prepared, run webinars interactively and show the great value of your webinar, more and more participants will be willing to pay for your entire webinars and then it's a good chance to create paid webinars to monetise your expertise.
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.
