Female Tennis Player, US Open 2011

All the courts used by the US Open are lighted, meaning that television coverage of the tournament can extend into prime time to attract higher ratings. This has recently been used to the advantage of USA Network—and now, ESPN2—on cable and especially for CBS, the American broadcast television outlet for the tournament for many years, which used its influence to move the women's singles final to Saturday night to draw better television ratings.
In 2005, all US Open (and US Open Series) tennis courts were given blue inner courts to make it easier to see the ball on television; the outer courts remained green.
The USTA National Tennis Center was renamed in honor of four-time tournament champion and tennis pioneer Billie Jean King during the 2006 US Open.
