In Britain, a form of regional sporting competition based upon fixtures between teams representing counties, politically designated and named areas (such as Somerset, or Yorkshire). County championships have been organized in various sports such as hockey, rugby union, and cricket. English first-class cricket in particular was organized, from 1890 onwards, on the basis of its County Championship, a form of the game played over three days (from 1993, four days). The profile of this form of the game has diminished in the context of international fixtures and the rise of one-day and evening-based forms of competition. In 2008, data from the British Market Research Bureau confirmed the popularity of the Twenty20 format over the County Championship: 23 per cent of English adults (9.6 million) reported having followed Twenty 20, only 20 per cent still following the traditional County Cricket Championship.
