On some systems you can have plenty of viewers - Community Rail is big, but the online awards, surely, are not going to exceed 10,000 big?
Zoom Video Webinars allow you to easily conduct large online events with video, audio and screen sharing for up to 100 video participants and 10,000 attendees
The features in Webinar are tailored for managing large audiences with branding, registration, host controls, polls, question & answer, raise hand, chat, recording and reporting

CRN‡ people and guest speakers. I'm not sure if video participants can be switched during the event to have a pool of people from shortlisted groups (current and next category at any time) but I'm sure the technical team will come up with something.
