A very popular British TV sitcom first aired in 2008, based on the lives of 4 ordinary middle class teenage boys (Will, Simon, Jay, and Neil) living in the suburbs of London. The plot follows the boys at their everyday lives at the fictional Rudge Park Comprehensive and on various school trips away, group outings and many other things which, though achieveable by normal standards, always seem to go wrong for them eg, Will shits himself in a GCSE exam. The show has been nominated for 'Best Situation Comedy' at BAFTA twice, in 2009 and 2010. At the British Academy Television Awards 2010, it won the Audience Award, and in 2010 the show won the Best Sitcom award at the British Comedy Awards. In the 2011 British Comedy Awards, the show also won the award for Outstanding Contribution to British Comedy. Despite the show finishing in 2010 after it's 3rd series, The Inbetweeners Movie was released in 2011 and grossed a huge £45,000,000 despite it's small budget of just £3,500,000
