100 Years Of The BBC: Key Moments

The BBC celebrates its centenary on October 18, after 100 years of technological innovation, ambitious programming -- and controversy.

The BBC was officially formed on October 18, 1922 by a group of entrepreneurs but it was only on November 14 that the first radio programme was broadcast.

At 6:00 pm, a news bulletin started and the first words -- "This is 2LO, Marconi House, London calling" -- crackled through radio sets.

"It was read once and it was repeated immediately after at half the speed because the technology was not great," said James Stirling, who is in charge of the centenary celebrations.

Ten years later in 1932, technology had advanced sufficiently to allow king George V to address the British empire for the first time on the radio.

That kickstarted the BBC Empire Service -- the forerunner of the BBC World Service.

The king's voice was heard for the first time by millions of people at the same time.

Television programmes began in 1936.

Britain's prime minister, Neville Chamberlain, announced the start of the war on the BBC on September 3, 1939.

During the conflict, the BBC became an essential source of news, and not just for Britons.

On June 18, 1940, exiled French General Charles De Gaulle launched his call for resistance to the Nazi German invasion on the airwaves of the BBC.

"Radio Londres" also broadcast the programme "Les Fran?ais parlent aux Fran?ais" ("The French speaking to the French") and in early June 1944, a coded message calling for railway installations to be sabotaged before the D-Day landings.

Queen Elizabeth II's coronation on June 3, 1953 was the first to be seen live on television.

"It's such a key moment in BBC history, in broadcasting as well," said Stirling.

Some 20 million people across Europe watched while in Britain viewers gathered with friends and neighbours to witness the spectacle on television.

My grandparents bought a TV for the occasion," said Stirling. "It's very important in terms of history and from a technology perspective."

Fast-forward to 1981 and the wedding of the then Prince Charles -- now King Charles III -- to Lady Diana Spencer was seen by 750 million people around the world.

More records were broken in 1995 when the BBC broadcast an explosive interview with princess Diana.

"There were three of us in this marriage so it was a bit crowded," she told the Panorama programme, referring to Charles' affair with Camilla Parker Bowles.

Diana also spoke of her own infidelities as the couple's marriage collapsed, how she thought Charles was not fit to be king and that she wanted to be "a queen of people's hearts".

A report published last year lifted the lid on the deceptive methods that journalist Martin Bashir used to secure the interview and criticised the BBC for its handling of the affair.

In 2007 the BBC launched its streaming and on-demand site BBC iPlayer to complement its traditional broadcasting.

The platform has developed in line with competition from other services such as Netflix and Disney+, which have transformed viewing habits.

The eccentric presenter Jimmy Savile was a fixture on children's television from the 1960s but in 2012, a year after his death, a scandal erupted.

Savile, who regularly presented the hit music show "Top of the Pops" and had his own programme "Jim'll Fix It", was unveiled as a predatory paedophile who had raped and molested minors for decades.

The BBC was accused of a cover-up, apologised and launched an independent investigation which concluded in 2016 that a culture of fear and celebrity deference had enabled Savile's activities.
