A webinar is basically a seminar that is conducted over the Internet.

Short for Web-based seminar, a webinar is a presentation, lecture, workshop, or seminar that uses video conferencing software to be transmitted over the Web.

One of the key features of a webinar is the interactive element, giving viewing the ability to both receive and discuss information in real-time.

Webinars are particularly good at bringing together audiences in different locations, this means that they are good for long distance learning.
