LBC

From the Wikipedia page

LBC (originally the London Broadcasting Company) is a London-based national phone-in and talk radio station. It was the UK's first licensed commercial radio station, beginning broadcasting on Monday 8 October 1973,[1] a week ahead of Capital Radio. The launch of LBC also saw the beginning of IRN's broadcasting, as LBC provided the service to independent local radio stations nationwide.

LBC is owned by Global and has a like-branded sister station – LBC London News – which is dedicated to rolling news, travel and weather, and is broadcast in London on medium-wave and DAB.
