and across Wales. The majority of the orchestra's concerts are recorded for broadcast on BBC Radio 3, BBC Radio Wales and BBC Radio Cymru. Since January 2009 the administrative base of the NOW has been the BBC Hoddinott Hall, in the Wales Millennium Centre, Cardiff. History The first broadcast in Wales was on 13 February 1923 from the radio station 5WA at 19 Castle Street, Cardiff. In March 1924 they moved into larger premises at 39 Park Place, later taking over most of the properties on the street. During this time, the region was served from bases around Wales. During World War II, the regional services all ceased and broadcast the Home Service from London, although some Welsh content was included. The BBC's Bangor base played host to the BBC Variety Department during the war, although this fact was never officially announced. Following the end of the Second World War, the BBC Home Service continued its regional opt-outs, including an opt-out service for Wales. This opt-out continued after the change from the Home Service to Radio 4 and paved the way for two full-time radio services - BBC Radio Cymru in 1977, followed a year later by BBC Radio Wales. In 1952 they bought a 10-acre site at Baynton House in Llandaff, Cardiff to house all of its operations in the city. The BBC has also occupied other locations in Cardiff such as; Celtic Road in Gabalfa, Newport Road in Roath, above a Spar shop in Llandaff village, and Charles Street in the city centre. The first television signals in Wales came on 15 August 1952 from the newly constructed Wenvoe transmitter. The transmitter itself broadcast the national BBC Television service. Wales would gain some significance when, in 1957, the BBC West region from Bristol was established including a daily five-minute news bulletin for Wales, followed five years later by the launch of the daily magazine programme, Wales Today. The launch of BBC Wales on 9 February 1964 provided a specific television service for the country. The new service was heavily promoted (proclaiming that Wales gets its very own TV service in 1964!) with animated promos using the sound of Welsh choirs to explain about interference from the mountains. Two years later in 1966, BBC Cymru Wales' new headquarters at Broadcasting House in Cardiff opened and the first colour broadcast for Wales followed in 1970. Prior to 1982, BBC Cymru
