BrightTALK does not require any proprietary software for an audience member to view a webinar.
The BrightTALK Pro Webinar tool does not require Adobe Flash for audience to viewing. Outdated versions of Internet Explorer 10 or earlier are the exception as these browsers still require flash to view videos. Make sure your audience is using Internet Explorer 11+, Chrome, Safari or Firefox.
iOS and Android devices now support the viewing of live and recorded BrightTALK Pro webinars, as well as recorded standard (slides & audio) webinars.
