A host of TV legends were on hand to start a spectacular light show in Crystal Palace last night.

Sir David Attenborough, Chris Evans, Professor Brian Cox, Greg Dyke and Sir Peter Bazalgette were at the event, to mark the landmark transmitter's switch from analogue to digital signals, saw lights beamed across south London from the 219 metre-tall mast.

Acclaimed wildlife broadcaster Sir David Attenborough pressed the red button to turn the skies a myriad of colours, marking the end of 75 years of analogue TV broadcasting in the region.

The guests were part of a special ceremony hosted by UK TV broadcast network operator, Arqiva.

They recalled their greatest ever TV moments, with Sir David recalling the "moment a man walked down a ladder and stepping on to the moon" and Professor Brian Cox treasuring the Apollo 13 splashdown.

Former BBC director general Mr Dyke shared his precious TV moment of Geoff Hurst’s goal in the 1966 World Cup and his favourite comedy, The Likely Lads.

He said: "This is a momentous moment in terms of choice of TV.

"We are all guilty of forgetting the range and quality of television we have in this country and it’s all got a lot better with the digital switchover."

Former Playschool presenter Floella Benjamin recalled the time her stage show in the West End was halted because tennis legend Arthur Ashe was on the brink of beating Jimmy Connors and the show stopped so they could watch the historic TV moment.

Host Chris Evans quizzed Sir David Attenborough about his 60 years in broadcasting and how he introduced Match of the Day to BBC2, snooker to television with Pot Black, floodlit rugby league and the Old Greywhistle Test.

Professor Brian Cox said: "TV that’s watched by millions of people, so significant fractions such as 10 or 20 percent of the population, is overwhelming important.

"The argument that’s often made is that in a digital world, with the Internet, you can just choose what you want to watch.

"But I don’t think that’s genuine choice really.

"I think that the foundation of choice is that you see things that you wouldn’t normally have watched."

Arqiva CEO, John Cresswell, said: "This is a broadcasting landmark and digital switchover is an amazing engineering and technical feat and a fantastic story of British success.

"The UK has an amazing record of producing fantastic television.

"Freeview is the platform of choice across the UK and the investment we have just made will ensure it continues to be relevant for the next twenty years."
