'''BigBlueButton''' is an [[open source]] [[web conferencing]] system. It is based on [[Linux|GNU/Linux]] operating system and runs on Ubuntu 16.04.  In addition to various web conferencing services, it has integrations for many of the major learning and content management systems.  Latest release of BigBlueButton is version 1.1.<ref name="BigBlueButton 1.0 Released">{{Cite web|url=https://bigbluebutton.org/2017/05/25/bigbluebutton-1-1-released/|title=BigBlueButton 1.1 Released|last=|first=|date=|website=bigbluebutton.org|archive-url=|archive-date=|dead-url=|access-date=2016-08-08}}</ref>

== Features ==
BigBlueButton supports multiple audio and video sharing, presentations with extended whiteboard capabilities - such as a pointer, zooming and drawing - public and private chat, desktop sharing, integrated VoIP using [[FreeSWITCH]], and support for presentation of PDF documents and Microsoft Office documents. Moreover, users may enter the conference in one of two roles: viewer or moderator.

As a viewer, a user may join the voice conference, share their webcam, raise their hand, and chat with others. As a moderator, a user may mute/unmute others, eject any user from the session, and make any user the current presenter. The presenter may upload slides and control the presentation.<ref name="bigbluebuttonorg">

Although its components are open source, the BigBlueButton client depends on a [[browser plugin]] for the [[Adobe Flash]] platform. The BigBlueButton server runs on Ubuntu 10.04 64-bit and can be installed either from source code or from Ubuntu packages. BigBlueButton is also downloadable as a Virtual Machine (VM) that runs within [[VMware Player]] on PC and Unix computers and within [[VMWare Fusion]] on Macs.<ref name="bigbluebutton_install_vm">

</ref>  The BigBlueButton server can also run within a cloud environment, such as Amazon EC2, by installing it on an Ubuntu 10.04 64-bit instance.

== Architecture ==
Similar to [[Openmeetings]], BigBlueButton uses [[Red5 (media server)|red5]], an open source implementation of Adobe's Flash Media Server, to support its real-time collaboration.<ref name="osflashorg">It also uses [[redis]], the open-source key-value data store software, to maintain an internal list of its meetings, attendees, and any other relevant information.

== History ==
In 2007 the project was started at [[Carleton University]] by the Technology Innovation Management program.<ref>Nettleton, Rob [http://edc.carleton.ca/blog/index.php/2010/06/04/bigbluebutton/ "BigBlueButton"], ''EDC Blog'', June 4, 2010.</ref>
The first version was written by Richard Alam (it was initially called the Blindside project) under the supervision of Tony Bailetti.<ref name="osbrca">

</ref>

In 2009 Richard Alam, Denis Zgonjanin, and Fred Dixon uploaded the BigBlueButton source code to Google Code and formed Blindside Networks, a company pursuing the traditional [[Business models for open source software|open source business model]] of providing paid support and services to the BigBlueButton community.<ref>Dixon, Fred [http://www.osbr.ca/ojs/index.php/osbr/article/view/1314/1259 "Lessons from an Open Source Business"], ''Open Source Business Resource'', April, 2011.</ref>

In 2010 the core developers added a whiteboard for annotating the uploaded presentation. Jeremy Thomerson added an application programming interface (API) which the BigBlueButton community subsequently used to integrate with [[Sakai Project|Sakai]],<ref name="sakaiprojectorg">
