Puzzle of the Week #95 - The Photograph

A mother and daughter are sat together on the settee, flicking through a photo album, whilst a massive international event plays out live on the television.

‘See this photo?’ says the mother, ‘this was taken on New Year’s Eve 1999. What a night!’

‘How old were you in that photo Mum?’ asks the daughter.

‘Well, funny you should ask that, I was halfway between your age now and my age now, precisely to the day’.

Since their dates of birth are 12th March 1980 and 4th May 2005, what was on the TV?
