The increase in technology has also allowed many decisions in sports matches to be taken, or reviewed, off-field, with another official using instant replays to make decisions. In some sports, players can now challenge decisions made by officials. In Association football, goal-line technology makes decisions on whether a ball has crossed the goal line or not.  The technology is not compulsory, but was used in the 2014 FIFA World Cup in Brazil, and the 2015 FIFA Women's World Cup in Canada, as well as in the Premier League from 2013–14, and the Bundesliga from 2015–16.  In the NFL, a referee can ask for a review from the replay booth, or a head coach can issue a challenge to review the play using replays. The final decision rests with the referee.  A video referee (commonly known as a Television Match Official or TMO) can also use replays to help decision-making in rugby (both league and union).  In international cricket, an umpire can ask the Third umpire for a decision, and the third umpire makes the final decision.  Since 2008, a decision review system for players to review decisions has been introduced and used in ICC-run tournaments, and optionally in other matches.  Depending on the host broadcaster, a number of different technologies are used during an umpire or player review, including instant replays, Hawk-Eye, Hot Spot and Real Time Snickometer.  Hawk-Eye is also used in tennis to challenge umpiring decisions.
