The BBC suffered a great deal from a string of occasions where programmes (non news ones I might add) had been found to be making up competition winners, contributors and viewer/listener comments. So it was a widespread change of policy and tightening up of editorial control, and all staff had to attend a training course called Safeguarding Trust. It addressed all manner of things like editing of photographs, supporting live programmes with senior editorial staff (some early morning/late night local radio shows were simply a presenter and no one else), and editing of sequences which might lead viewers to thinking something had happened in an order at odds with what had actually happened.
The big changes though were the effective banning of As-Live treatments, particularly in news and current affairs programmes, and the suspension of phone-in competitions (some of which never returned).
As Live treatments were once quite commonplace in regional news, where a reporter on location would send a single-take piece to camera, possibly containing an interview and it would start and end with a 'hold'. The director would run it early, mix it into a screen and the presenter would throw to it as if the reporter was actually there on a live link. In many cases the reporter
actually still there, preparing their report for a later edition, but this argument fell flat with managers who decided that the viewer would feel misled. Some smaller regions without live facilities used As Live treatments to mix up their reporting styles within a programme and so the ban led to a measure of 'shape' being lost from the overall programme, where it just became a series of links, packages and voiceover "news in brief" type items. News 24 had for years run live clips again later on "As Live" by clipping them up and repeating them. "Turnarounds" still happen, but they now start repeats on the first (or subsequent) answer, cut off any thank you from the end and introduce them generically.
Local Radio suffered quite badly as a result. Lone presenters had to be supported by a producer the other side of the glass. Phone in competitions were suspended across the BBC for months. When they were allowed again, the controls to get compliance and permission to run one meant a lot of local stations didn't bother..
A lot of things changed very much for the better. No one could argue that making up comments, competition winners, or contestants is a great way to make a programme. Introducing recorded programmes on networks where phone in is usually encouraged (such as Radio 5 Live) is now done by saying "This is a recorded programme, so please don't text or call" so that the viewer doesn't waste their money. Any phone vote shows (like Strictly) have lengthy Terms and Conditions which viewers are invited to read and it's made clear how much it costs to vote.
