Andrew Breitbart (February 1, 1969 – March 1, 2012) was a conservative media publisher, activist and internet entrepreneur who ran his own news aggregation site, Breitbart.com, as well as five other websites: Breitbart.tv, Big Hollywood, Big Government, Big Journalism, and Big Peace. He was viewed as a one-man conservative gang who took to the task to fight what he saw as the liberal-dominated coverage of politics and culture.

Breitbart first came to prominence in the political world as an editor for the Drudge Report, a political tipsheet frequented daily by journalists, cable television bookers and politicians. He later helped Arianna Huffington launch the Huffington Post website. His internet investigations led to the resignations of former New York Rep. Anthony Weiner and former U.S. Agriculture Department official Shirley Sherrod.

Breitbart died unexpectedly at the age of 43 after collapsing on the sidewalk near his Southern California home. The timing of his death sparked swift conspiracy theories as he had previously announced that he would be releasing what he described as damning videos of Barack Obama that would have sunk Obama's 2012 re-election campaign.
