In 1876, lawn tennis, a game devised by Major Walter Clopton Wingfield a year or so earlier as an outdoor version of real tennis and originally given the name "Sphairistikè", was added to the activities of the club. In spring 1877, the club was renamed "The All England Croquet and Lawn Tennis Club" and signalled its change of name by instituting the first Lawn Tennis Championship. A new code of laws, replacing the code administered by the Marylebone Cricket Club, was drawn up for the event. Today's rules are similar except for details such as the height of the net and posts and the distance of the service line from the net.
