David Attenborough is 90 today. The world's most celebrated naturalist, he's been making and presenting groundbreaking TV wildlife and natural history documentaries for over 60 years. Not only has he informed, educated and entertained generations of viewers worldwide, he's also worked as a senior TV exec. He became controller of the BBC's second TV channel when it launched in 1965 and he was responsible for taking the decision on commissioning new shows like Monty Python, and TV snooker - he chose snooker when colour TV began in 1966 as an obvious way to encourage people to buy colour TV sets
And he's still travelling the world making new documentaries like the recent Great Barrier Reef series. It's a cliche to say someone's a legend in their own lifetime, but if anyone qualifies then surely he does. Happy 90th, Sir David, and long may you continue
