Five notable changes that took place in Britain in the 77 years that elapsed between Wimbledon titles for Fred Perry and Andy Murray, who ended Britain's drought on Sunday:1. MANY BIRTHDAYS: Queen Elizabeth II was 10 at the time of Perry's victory in 1936 and still known as Princess Elizabeth. Her coronation was in 1953.2. MANY WINNERS: A total of 39 different men representing 12 different countries won the men's title at Wimbledon, including one from the now-nonexistent country of Czechoslovakia (Jan Kodes).3. CHANGES IN PARLIAMENT: The office of Prime Minister exchanged hands 16 times. Some notables: Winston Churchill, Margaret Thatcher.4. A NEW WORLD: More than a dozen countries in Africa and large chunks of the Caribbean, including Jamaica, were granted independence from the British Empire.5. PRICE IS RIGHT: Price for a grounds pass has gone from 3 shillings to 8 pounds ($12). The British stopped issuing shillings for circulation in 1967.
