The BBC marked the 90th anniversary of its first ever transmission yesterday, beset by doubts about its future after a series of scandals surrounding the way it has reported child sex abuse allegations.

What was then known as the British Broadcasting Company crackled into life on November 14, 1922, with a radio news bulletin featuring stories about a train robbery, a “rowdy meeting” involving Winston Churchill and billiards scores.

But 90 years later the BBC – now the world’s largest broadcasting organisation – faces one of the most serious crises in its history as it seeks to defend its reputation and the public funding that sustains it.

The BBC was first hit by scandal last month over a decision by its flagship current affairs programme, Newsnight, to shelve an investigation into claims of paedophilia surrounding its late television star Jimmy Savile.

Savile died in 2011 and police now believe he abused hundreds of children.

Weeks later Newsnight was forced to retract false allegations that a senior Conservative politician from the era of former prime minister Margaret Thatcher abused children at a care home in Wales in the 1970s.

The BBC’s director-general George Entwistle resigned on Saturday after 54 days in the job and the corporation has launched a series of investigations into both of the scandals, while it searches for a new leader.

The broadcaster faces further pressure over Entwistle’s £450,000 (€565,000) payoff – the equivalent of a year’s salary.

BBC staff were meanwhile asked not to fan the crisis with any new revelations on social media, in a memo from their new acting head of news that was itself swiftly leaked. Fran Unsworth took over after Head of News Helen Boaden “stepped aside” over the crisis on Monday.

The magnitude of the scandal reflects the extent to which the BBC has become part of the fabric of British national life over the past 90 years.

The BBC is also part of British families’ budgets, with all households with a television obliged to pay an annual “licence fee” of £145.50, the equivalent of just under 40p per day.

The first BBC broadcast, at 6 pm on November 14, 1922, was by its then director of programmes Arthur Burrows, one of only four staff of a company set up a few weeks earlier by early radio manufacturers.

Publicly funded under a royal charter, the BBC has nearly 23,000 employees and a global audience of around 239 million people, according to the corporation’s own figures.

Meanwhile Michael Souter, a former presenter for BBC Radio Norfolk in eastern England, was on Tuesday charged with sexually abusing children, although it was not related to the ongoing Savile investigations, police said.
