Instant Replay
Computer-assisted video tracking technology has improved to the point that it can determine the position of a ball at impact with a margin of error less than five millimeters. Accordingly, starting with the NASDAQ-100 Open in March 2006, most top-level tournaments allow systems such as Hawk-Eye to be used to settle disputed line calls.
Players are allowed to appeal to Hawk-Eye on disputed calls with a limitation: They lose the privilege if the appeal goes against them three times per set, with one more challenge allowed during a tie-breaker.
In the 2006 NASDAQ-100 Open, challenges by men were upheld 38% compared to 27% for women (skewed by Maria Sharapova, who went 0 for 11).
At the Championships, Wimbledon 2008, in the mens singles challenges were successful 29% of the time with an average of 6.6 challenges per match, in the women singles challenges were successful 20% of the time with an average of 3.8 challenges per match.

Famous quotes containing the words instant and/or replay:
““Heaven nor hell shall impede my designs,” said Manfred, advancing again to seize the princess. At that instant the portrait of his grandfather ... uttered a deep sigh and heaved its breast. ... Manfred ... saw it quit its panel, and descend on the floor with a grave and melancholy air.”
—Horace Walpole (1717–1797)
“Everything our children hear, see, and feel is recorded onto a cassette. Guess who is the big star in their movie? You are. What you say and, more important, what you do, is recorded there for them to replay over and over again. We all have videocassettes. Adults just have larger libraries of tapes available.”
—Stephanie Martson (20th century)
