A webinar is an event held on the internet which is attended exclusively by an online audience. This distinguishes it from a webcast, which also includes the presence of a physical audience. Other terms used as alternatives for webinar are web event, online seminar, webcast, web lecture and virtual event.

Online participation

Participants follow webinars via a PC, Mac, tablet or smartphone, and can see and hear the speaker(s) thanks to audio and video feeds. In addition to the video images, PowerPoint slides can be broadcast which run in sync with the rest of the presentation. You can also make use of the screen capture functionality which enables you to show your viewers an application or website.
