10. Ryan Giggs versus the Internet
When news of a super injunction preventing the media from naming a married Premier League star accused of infidelity in the spring of 2011, few would have imagined that Manchester United's veteran winger Ryan Giggs was the man in question.
Yet it was indeed the 37-year-old, still playing sublime football despite his advancing years, at the centre of it. Model and former Big Brother contestant Imogen Thomas was prevented from giving any details of the alleged affair, while newspapers fumed about the courts gagging them despite the decidedly grey areas in UK privacy law.
The super injunction appeared to be holding firm - despite an MP alluding to his name on TV news quiz Have I Got News For You - and Giggs's identity seemed set to remain out of the public domain.
That is where social media came in, with anonymous users posting his name on Twitter - as well as names of several other high-profile people in the worlds of sport and entertainment who had obtained similar injunctions.
If Giggs had left it at that he might have got away with it, but his lawyers' ill-advised attempts to try and force California-based Twitter to release personal details of those who had breached the injunction - with a view to forcing contempt of court prosecutions - the internet went mad.
In what can only be described as cyberspace's answer to the end of classic 1960 Stanley Kubrick movie Spartacus, tens of thousands started tweeting Giggs's name, knowing that it would be impossible and impractical for all of them to face action. That movement prompted MP John Hemming to name Giggs in Parliament, thus allowing media to report the name and blowing the debate wide open.
The sad truth is that nobody would have cared about Giggs being an adulterer - after all, everyone from David Beckham downwards has been caught with their pants down at some stage - with the possible exception of Giggs's wife. In fact, it would probably have pepped up the reputation of a star who has always seemed as relentlessly dull off the pitch as he is brilliant on it.
But now, however, he will always be remembered as the sad and slightly desperate figure who tried to stop the flow of information on the internet.
