The History of Tennis
The modern game of tennis originated in Birmingham, England, in the late 19th century as "lawn tennis". It had close connections both to various field games such as croquet and bowls as well as to the older racket sport of real tennis. During most of the 19th-century, the term "tennis" referred to real tennis, not lawn tennis.
The rules of tennis have not changed much since the 1890's. Two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tie-break in the 1970's. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point challenge system, which allows a player to challenge the line umpire's call of a point.
