From royal dramas to wartime: 1922-46

On 14 November 1922 the first daily radio service, with the code name 2LO, was launched by the British Broadcasting Company (BBC) in London.

The wireless quickly became a social and cultural phenomenon and the monarch learned to use the new medium to address his people.

On 23 April 1924 George V broadcast for the first time.

Millions heard his voice as he opened the Wembley Empire exhibition.

Traffic was stopped on Oxford Street as crowds gathered to listen on loud speakers.

Four years later, however, the BBC clashed with the government over editorial independence during the General Strike of 1926. With no regular newspapers the country turned to the wireless.

Some politicians, particularly Chancellor Winston Churchill, wanted to take it over. But the BBC's founder Lord Reith fought a tough battle to keep its independence.

Passions also ran high at sporting events, and the first running commentary on a game event was a rugby match in 1927. England v Wales at Twickenham.

Another first was delivered in 1932, when George V broadcast his Christmas message, which had been scripted by Rudyard Kipling.

In May 1935 the country celebrated the King's silver jubilee but within a year George V had died. The BBC broadcast the first royal funeral on 28 January 1936.

Edward VIII acceded to the throne but the constitution prevented the King from marrying American socialite Wallis Simpson who was a divorcee. He abdicated on 11 December 1936.

The coronation of George VI took place in 1937.

On 6 June 1944 the Allied forces landed on the beaches of Normandy to begin the liberation of Europe. After D-Day, the BBC's war correspondents reported the events of the last punishing year.
