Prince William has marked his thirtieth birthday. And he has a lot to celebrate. Among his list of achievements is being the first future British monarch to attend Eton College, an exclusive private school near London. And with an honours degree from St Andrew's University, he's also the most academically accomplished British royal. Born William Arthur Philip Louis on June 21st, 1982, he is the first child of Prince Charles and Princess Diana. Over the years, he's attracted intense media attention, not least when at the age of 15 his famous mother died in a car accident in Paris. In 2006, he graduated from Sandhurst military academy and spent two years training for his future role as head of the armed forces. And four years later, he proposed to long-time girlfriend Kate Middleton, revealing his sense of humor when talking to the press about the couple's engagement. Reporter: "Prince William, why did it take you so long to propose?"
PRINCE WILLIAM: "I don't remember how many years it has been, forget the memory, I also didn't realise it was a race otherwise I probably would have been a lot quicker."
REPORTER: The wedding breathed new life into the monarchy, attracting a worldwide audience of 2 billion people. Prince William has piloted helicopters, raced canoes in Canada and mingled with celebrities in California. And the next 30 years may well see him ascend the British throne. Tara Cleary, Reuters.
