What the blazes is that, a live webinar?

Webinar… an atrocious word in itself, means an online/web seminar.

As seminar is a fairly informal form of an academic lecture, and generally contains a component of interactivity – either there is an opportunity for questions at the end of presentations, or later in the hallway.

In context, so far so good. You can do that online. Fine.

So why do companies now need to put the adjective “live” in front… what does that mean?
