Goal-line technology

<p>In <a href="/facts/Association_football/yttjeD0D">association football</a>, goal-line technology (sometimes referred to as a Goal Decision System) is the use of electronic aid to determine if a <a href="/facts/Scoring_in_association_football/2d809Ayr">goal</a> has been scored or not. In detail, it is a method used to determine when the ball has completely crossed the goal line in between the goal-posts and underneath the crossbar with the assistance of electronic devices and at the same time assisting the <a href="/facts/Referee_(association_football)/urt4skQf">referee</a> in awarding a goal or not. The objective of goal-line technology (GLT) is not to replace the role of the officials, but rather to support them in their decision-making. The GLT must provide a clear indication as to whether the ball has fully crossed the line, and this information will serve to assist the referee in making their final decision.
</p><p>Compared to similar technology in other sports, goal-line technology is a relatively recent addition to association football, its integration having been opposed by the sport's authorities. In July 2012, the <a href="/facts/International_Football_Association_Board/wneLwbDe">International Football Association Board</a> (IFAB) officially approved the use of goal-line technology, amending the <a href="/facts/Laws_of_the_Game_(association_football)/259Fc4t8">Laws of the Game</a> to permit (but not require) its use. Due to its expense, goal-line technology is only used at the highest levels of the game. Goal-line technology is currently used in the top European domestic leagues and at major international competitions such as, since 2014, the <a href="/facts/FIFA_World_Cup/pGI0SF7r">men's</a> and <a href="/facts/FIFA_Women%27s_World_Cup/38auvt8v">women's</a> FIFA World Cups.
