As we saw in the previous activity, web conferencing experience typically integrates audio, and video also has whiteboards and can be recorded, including screen sharing and file sharing.
Web conferences are best for smaller groups (one-to-one or one-to-small group interactions), so if you intend to simulate a physical classroom, and also accommodate larger groups of people across dispersed locations, a webinar or webcast is a better option.

A webinar usually includes an instructor delivering content to a broader audience than the web conferencing option. It can offer a high degree of real-time interaction if you want to include these elements in your content delivery methodology.

What I like about the following article is that it provides an easy-to-read and exciting content not only to understand webinars better but also how to use it as a marketing tool.
