BBC Radio 2 is one of the BBC's national radio stations and the most popular station in the United Kingdom. Much of its daytime playlist-based programming is best described as Adult Contemporary or AOR, although the station is also noted for its specialist broadcasting of other musical genres. Radio 2 broadcasts throughout the UK on FM between 88.1 and 90.2MHz from studios in Western House, adjacent to Broadcasting House in central London. Programmes are relayed on digital radio via DAB, Sky, Cable TV, IPTV, Freeview, Freesat and the Internet. The station's programming is broadcast on a network of FM transmitters of up to 250 kW, the strongest FM signals in the EU.

The station was launched at 05:30 on 30 September 1967, and evolved from the Light Programme, with some of the Light Programme's music shows transferring to the newly launched Radio 1. The first show had started at 05:30am (on the Light programme) but continued with Breakfast Special from Paul Hollingdale as Radio 1 split.

In early years, much programming and music was common to both stations, particularly on the shared FM frequency. Radio 1 was targeted at the audience of pirate radio stations whereas Radio 2 settled down as a middle-of-the-road station playing laid-back pop/rock, folk and country, jazz and big-band music, easy listening, light classics, and oldies, with significant amounts of comedy and sport. Notable broadcasters on Radio 2 in the 70s and 80s were Ray Moore on early breakfast, Terry Wogan on breakfast, replaced by Ken Bruce and later Derek Jameson; Jimmy Young and his lunchtime news and current affairs show; 'Diddy' David Hamilton on mid-afteroons, John Dunn at what became known as drivetime. Radio 2 became the first national 24-hour radio station in the UK in 1979.
