The ATP Tour is a worldwide top-tier tennis tour for men organized by the Association of Tennis Professionals. The second-tier tour is the ATP Challenger Tour and the third-tier is ITF Men's World Tennis Tour. The equivalent women's organisation is the WTA Tour.
The ATP Challenger Tour, known until the end of 2008 as the ATP Challenger Series, is a series of international men's professional tennis tournaments. The Challenger Tour events are the second-highest tier of tennis competition, behind the ATP Tour. The ITF World Tennis Tour tournaments are on the entry-level of international professional tennis competition. The ATP Challenger Tour is administered by the Association of Tennis Professionals. Players who succeed on the ATP Challenger Tour earn sufficient ranking points to become eligible for main draw or qualifying draw entry at ATP Tour tournaments. Players on the Challenger Tour are usually young players looking to advance their careers, those who fail to qualify for ATP events, or former ATP players looking to get back into the big tour.
The racket sport traditionally named lawn tennis, invented in Croydon, now commonly known simply as tennis, is the direct descendant of what is now denoted real tennis or royal tennis, which continues to be played today as a separate sport with more complex rules. Most rules of (lawn) tennis derive from this precursor and it is reasonable to see both sports as variations of the same game. Most historians believe that tennis was originated in the monastic cloisters in northern France in the 12th century, but the ball was then struck with the palm of the hand; hence, the name jeu de paume. It was not until the 16th century that rackets came into use, and the game began to be called "tennis." It was popular in England and France, and Henry VIII of England was a big fan of the game, now referred to as real tennis.
