Zoom webinars differ from Meetings in two aspects: security and possibilities of interaction. Attendees in a webinar haven't got access to camera and microphone and can normally interact only through chatt or Q&A. For delivery of a presentation or when interaction is not needed or desired, webinar is a good choice. Examples of these are lectures open to the public or doctoral thesis defenses.

You can hold webinars for up to 500 participants.
At Lund University, we have a number of webinar licenses up to 1,000 participants that we lend out when needed.
