Bloggingheads.tv is a political, world events, philosophy, and science video blog discussion site in which the participants take part in an active back and forth conversation via webcam which is then broadcast online to viewers. The site was started by the journalist and author Robert Wright and the blogger and journalist Mickey Kaus on November 1, 2005. Kaus has since dropped out of operational duties of the site as he didn't want his frequent linking to be seen as a conflict of interest. Most of the earlier discussions posted to the site involved one or both of those individuals, but since has grown to include a total of over one thousand individual contributors, mostly journalists, academics, scientists, authors, well known political bloggers, and other notable individuals.
