Hawk-Eye is an instant replay system used to determine whether the ball is in or out. Getty Images

Hawk-Eye also provides ball-tracking systems for cricket and football.
In football, the Hawk-Eye system uses seven different cameras to track the ball and determine whether it has crossed the line, but it's only in recent years the sport has embraced the greater use of technology to help referees. Image provided by Hawk-Eye
It was only after the 2010 World Cup that football's world governing body FIFA recognized the need for change.

"We love our guys in the game now, Roger, Rafa and the way they carry themselves but there's some entertainment value on the guys that don't carry themselves so well," Roddick said, mentioning himself, retired two-time grand slam winner Marat Safin and the man dubbed "Super Brat," John McEnroe. steve powell/getty images/file
"Johnny Mac is out here all the time still going nuts and people love it," said Roddick, referring to the 55-year-old McEnroe, who is now competing in seniors' events. Central Press/Getty Images/file
