'''BigBlueButton''' is an [[open-source software|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.

== 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">{{ cite web

The BigBlueButton server runs on Ubuntu 16.04 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 16.04 64-bit instance.

== Architecture ==
Similar to [[Apache OpenMeetings]], BigBlueButton originally used [[Red5 (media server)|red5]], an open source implementation of Adobe's Flash Media Server, to support its real-time collaboration.<ref name="osflashorg">{{ cite web | url = http://osflash.org/red5

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"] {{Webarchive|url=https://web.archive.org/web/20100814003302/http://edc.carleton.ca/blog/index.php/2010/06/04/bigbluebutton/ |date=2010-08-14 }}, ''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"] {{Webarchive|url=https://web.archive.org/web/20120501031838/http://www.osbr.ca/ojs/index.php/osbr/article/view/1314/1259 |date=2012-05-01 }}, ''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">

The BigBlueButton name comes from the initial concept that starting a web conference should be as simple as pressing a metaphorical big blue button.<ref name="name">
