The legal system in England and Wales has reached a landmark for open justice: from tomorrow, broadcasters can film in the Court of Appeal.
Our appetite for pictures of the guilty may not be satisfied by footage of a High Court judge speaking measured words.
From Amanda Knox to OJ Simpson we have become used to seeing foreign trials on TV - now the UK is beginning to allow cameras in courts
Social media users who knowingly break court orders by posting prohibited information online, such as the identities of James Bulger's killers, can "easily" be prosecuted, a legal expert has warned.
Joshua Rozenberg explained: "If you can show that somebody knew that there was a court order in force, as this man last week, who was very nearly sent to prison - in the end he got a suspended sentence and a hefty financial penalty.
"But if you know that there is a order saying you can't publish a picture of Jon Venables, then it is obviously more easy for the Attorney General to prosecute you."
Careless tweets have landed a host of celebrities in trouble in the past with comedian Alan Davies, Sir Bob Geldof's daughter Peaches and Sally Bercow all finding themselves in legal difficulties due to their online posts.
Social media users have also found themselves in contempt of a court - nine people admitted naming the woman raped by footballer Ched Evans on Facebook and Twitter.
They were all told to pay the victim £624 each.
The Attorney General said he was publishing legal guidance notes previously only issued to the media to "help stop people from inadvertently breaking the law."
Dominic Grieve QC said: "Blogs and social media sites like Twitter and Facebook mean that individuals can now reach thousands of people with a single tweet or post. This is an exciting prospect, but it can pose certain challenges to the criminal justice system.
"In days gone by, it was only the mainstream media that had the opportunity to bring information relating to a court case to such a large group of people that it could put a court case at risk.
"That is no longer the case and is why I have decided to publish the advisories that I have previously only issued to the media.
"This is not about telling people what they can or cannot talk about on social media - quite the opposite in fact, it's designed to help facilitate commentary in a lawful way.
"I hope that by making this information available to the public at large, we can help stop people from inadvertently breaking the law, and make sure that cases are tried on the evidence, not what people have found online."
The Attorney General will publish legal guidance notes online to help prevent Facebook and Twitter users from breaking the law by inappropriately commenting on court cases.
The Government's chief legal adviser Dominic Grieve QC will in future issue previously unpublished advisory notes in a bid to stop social media users from committing a contempt of court.
He said the move was designed to make sure that fair trials take place and will apply to court cases in England, Wales and Northern Ireland.
The advisories, which have previously only been issued to the media, are being put into the public domain so people avoid legal pitfalls by commenting on court cases in a potentially prejudicial manner.
The advisories will be published on the Attorney General's Office (AGO) section of the gov.uk website and also through the AGO's Twitter feed - @AGO_UK.
The Prime Minister's brother, Alexander Cameron QC, made an appearance in some of the first footage to be broadcast from the Court of Appeal since 1925.
Television pictures of a live case at the Court of Appeal have been broadcast for the first time since cameras were banned from the vast majority of courtrooms in 1925.
The landmark footage did not include any sound since the case in question involved sensitive details relating to a child.
The defendant was not in shot since the cameras in the court will focus on the lawyers' arguments and judges' summing up, decision and - in criminal cases - sentencing remarks.
A near-90-year ban on filming in court will be lifted today in what has been hailed as a "landmark moment for justice and journalism".
For the first time, cameras will be able to broadcast from one of the highest courts in the land, the Court of Appeal.
After years of campaigning by broadcasters BBC, ITN, Press Association and Sky News, cameras have been placed in five courtrooms at the Royal Courts of Justice.
From tomorrow cameras will be allowed to film at the Court of Appeal. After 90 years, the ban on filming proceedings there has been lifted. We will be able to see the legal arguments and the judge's ruling. But the defendants and witnesses will not be filmed.
And it could pave the way for cameras in other Courts.
ITV News' Paul Davies reports:
Footage film in the court room can be used in a news and current affairs context only and is banned from being used in other genres such as satire, entertainment or commercial use in advertising.
ITN chief executive John Hardie said: "Filming in courts has been a long time coming and is for the benefit of open justice and democracy. Never before will television viewers have had such an insight to justice being seen to be done."
Camera positions are to be operated by the court video journalist with both legal and journalistic qualifications.
