<human>:  What is the difference between a webinar and a podcast?
<bot>: The main difference between a webinar and a podcast is that a webinar is a live, interactive virtual event, while a podcast is an audio or video recording meant to be consumed at the listener or viewer's convenience. A webinar generally requires participants to register to take part, while a podcast can be downloaded or streamed without registering for anything. Webinars are also typically hosted by an expert or presenter and designed to offer educational and professional development material, as opposed to podcasts which tend to be more casual conversations or monologues.
