Media Archive - Radio Transmitter That Changed Our World

This is the story of how the British Broadcasting Company began, powered by Britain’s biggest radio transmitter, 2LO. Discover how radio became part of everyday life in our new Information Age gallery, opening 25 October 2014

On a foggy November night in 1922, the words ‘This is 2LO calling’ announced the arrival of the BBC. 2LO transmitted the BBC’s first radio programme, marking the beginnings of official, state broadcasting, and a new era for listeners at home.

See the 2LO radio transmitter on display in our Information Age gallery, which tells the story of how our lives have been transformed by information and communication technologies over the last 200 years. Visit or follow the conversation online via #smInfoAge to find out more.
