Tennis is a very old sport. Some actually say that it can be traced back a couple thousand years. The first accurate account of Tennis, though, can be traced back to around 1865. Two guys named Major Harry Gem and Augurio Perera created a game that combined rackets and a game like wall ball that they played on Perera’s lawn in the UK. In 1872, they created the first tennis club along with two doctors in Leamington Spa.   Old Tennis  
Sphairistike   In 1873, Major Walter Clopton Wingfield created a game similar to the game in the UK called sphairistike which meant skill at playing ball. The game was based on real tennis and many of the tennis terminology was created then. The name sphairistike was dropped because it was so hard to pronounce. Then, the name Tennis was derived from the French word Tenez which means look here. Whenever the server was about to serve, he would yell to the other player Tenez to get his attention. The scoring for Tennis (0, 15, 30, 40) was derived from early French players who would use a clock to keep score. The origin of the word love, which is used instead of zero, comes from the French word l'oeuf which means egg.  
  There are four major tournaments in the tennis world that take place once a year. The tournaments are the US Open, Wimbledon, Australian Open, and French Open. Together, these four tournaments are called the Grand Slam tournaments. The first US Open was played on 1881 in Rhode Island. The first Wimbledon tournament was played in 1877 in Wimbledon, London. The first French Open was played in 1891. Lastly, the first Australian open was played in 1905. Aside from the tiebraker rule change, the rules of tennis haven't changed ever since 1924.   Grand Slam Logos
