HBO's favorite British satirist isn't going anywhere. Just two weeks into its second season, Last Week Tonight has been renewed for a third and fourth season, each spanning one year and consisting of 35 episodes each (same as this year). That's a guarantee of more than 100 new episodes from now through the end of 2017.

In our sit-down earlier this month, Oliver noted that the show has hired more researchers with investigative journalist backgrounds to reinforce the long-form stories Last Week Tonight has become famous for. So far that's included pieces on Tobacco (embedded below) and Marketing to Doctors. Along the way, the show has also defended Radio Shack and chastised Sports Illustrated for its swimsuit issue.

Oliver has also promised "some long-term mayhem production things" à la last season's salmon cannon. The show can now plan for years ahead — theoretically, at least.
