In 2004, Skoll founded the company Participant to create films that increase public awareness of critical social issues and give audiences opportunities to get involved through education and social action campaigns. In 2005, Skoll's first Participant productions were released, with Syriana; Good Night, and Good Luck; North Country; and Murderball, together garnering 11 Oscar nominations. A year later, Skoll financed and played a key role in the creation of the environmental documentary, An Inconvenient Truth, which grew out of a slideshow developed by former U.S. Vice President Al Gore on the climate crisis. The film won the 2006 Academy Award for Best Feature Documentary. “ I would never have predicted that a film like "An Inconvenient Truth" would impact so many people,” Skoll told Philanthropy Roundtable.
