The term webinar is short for web-based seminar, a presentation, lecture, workshop or seminar that is transmitted over the web. Some argue that webinars might be one-way, from the speaker to the audience with limited audience interaction, so one-way broadcasts are perhaps more accurately called webcasts. Webinars themselves may be more collaborative and include polling and question-and-answer sessions to allow full participation between the audience and the presenter. The presenter may speak over a standard telephone line or webcam while pointing out information being presented on-screen. In some cases, a webinar might stream a presentation being given in a studio or onstage at a live event.
