Caerdydd is a Welsh language television programme set in Cardiff made by Fiction Factory for Welsh public service television station S4C. The series is "a stylish, new drama about modern, urban Welsh-speakers living in a bilingual city" following "a group of modern urban twenty- and thirtysomethings" with "their complex friendships and relationships [set] against a backdrop of relentless socialising". First commissioned by S4C's drama editor Angharad Jones in 2005, as part of a drive by S4C to reach a younger audience, the third series of Caerdydd started its run on S4C on 30 March 2008. A fourth series was commissioned and went into production in Spring 2008. It started broadcasting on 14 June 2009.
