BIL is an unconference organized and observed by the participants. It was founded in 2007 by Cody Marx Bailey, Todd Huffman, Bill Erickson and others who volunteered to help with the idea. BIL started as an unaffiliated unconference satellite to TED’s structured ‘invite only’ paid conference. BIL is an open, self-organizing, emergent arts, science, society, and technology conference. Anyone can come, and anyone is able to sign-up to speak, limited only by space and time. The unconference structure allows for egalitarian treatment of anyone in any role; everyone is encouraged to participate where they can, whether that's clean up, set up, getting coffee, listening, AV work, blogging the conference, registration, etc.
