lol u jelly brah? You jelly that the English are the most educated tennis crowd in the world? You jelly the English invented the game of tennis?
Technically the French Royal family and nobles invented tennis. It was known as jeu de pommes. The game may have existed in some form in other parts of the world but us Brits, like with Football, were the first to create the original official rules, tournaments, national teams and lay the ground work for the international competing sports scene.
I.E. Oldest football stadium (Wembley), oldest tennis tournament(Wimbledon), oldest golf venue, oldest cricket ground (Lords) etc. I am not sure about Twickenham for Rugby and Silverstone in regards to motor racing I am sure that these venues are among the oldest as well.
Did you know that of the 10 most popular sports in the world, 7 were "started" here. The other 3 I am guessing are Basketball, American football and baseball.
