Tennis World Team Tennis is a concept, devised by Billie Jean King, which came to fruition in the 1970's and has recently made somewhat of a comeback. The concept gradually died for various reasons in the late 70's but has been revised in a scaled-down form. The Team Tennis franchise is similar to US baseball and football, where teams based in various US cities compete against one another. Unlike baseball and football, team members get paid based on their performance rather than a fixed amount.
Teams consist of two male and two female players plus a coach.
Each team usually has one local player of each gender who serves as an alternate at home matches. There are two five-team divisions. Teams play two teams in the other division only once while playing home and away against the other seven teams, over a 4-week period following Wimbledon. The champion for the season is the team surviving the single-elimination playoff tournament. Prior to each set, a certain amount of time is allowed for player warm-ups.
