Blindside Networks started the BigBlueButton project in 2008 with one goal: to provide remote students a high-quality online learning experience.
BigBlueButton is an open source web conferencing system for online learning. It enables teachers to engage remote students with real-time sharing of audio, video, presentation, chat, desktop, and polls. BigBlueButton has deep integrations with Moodle via the BigBlueButtonBN Moodle plugin (ranked #9 in overall downloads at moodle.org)
Blindside Networks provides commercial hosting and support for BigBlueButton to the Moodle community.
