Digital Audio Broadcasting in Ireland is the only current form of digital radio transmission in the state. It was launched to the public on 30 November 2006, with trials taking place in 1998, 2001 and 2006. Currently, 56% of Ireland's population - mainly in Counties Cork, Limerick and the North East - can receive permanent DAB services. One permanent multiplex exists, operated by the national broadcaster RTÉ. The service began to be marketed in May 2007 by a collective of commercial broadcasters, digitalradio.ie; and receivers are now sold by most major electronics retailers.
