A webinar allows a speaker from the hosting organization/company to share PowerPoint presentations, videos, web pages, or other multimedia content with audiences that can be located anywhere.
Webinars typically have audio and visual components. They share the visual component of a webinar through a web conferencing tool or Internet browser. They usually broadcast the audio portion of a webinar through the audience’s computers (through speakers and media players) or through the telephone.
A webinar also allows the hosting organization/company to interact with an audience. The audience can ask the speaker or moderator (who is leading the webinar) questions in real-time through an instant messaging tool or e-mail.
