Goal - line technology - wikipedia Goal - line technology Diagram of a Goal Line Technology system based around sensors in the ball and goal frame. Most operational systems instead use cameras to track the ball In association football, goal - line technology ( sometimes referred to as a Goal Decision System ) is the use of electronic aid to determine if a goal 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 referee 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 his final decision. 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 International Football Association Board ( IFAB ) officially approved the use of goal line technology, amending the Laws of the Game 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 the 2014 Men 's, 2018 Men 's and 2015 Women 's FIFA World Cups.

In most cases, this is relatively unambiguous ( goal nets being a low - tech way of verifying that the ball passed the correct side of the goalposts ). Occasionally however situations occur when it is difficult for referees and their assistants to tell if a goal has been scored before a rebound, save, or defender 's clearance from the goal area. Rules Since 2012, goal - line technology has been permitted in matches. Text relating to goal - line technology can now be found within four of the Laws of the Game : Law 1 ( The Field of Play ) : permitting modifications to the goal frame. Law 2 ( The Ball ) : permitting the use of approved balls with integrated technology. Law 5 ( The Referee ) : requiring the referee to test a goal - line technology system prior to a match and not use it if a fault is found. Law 10 ( The Method of Scoring ) : permitting use of goal - line technology to verify whether or not goals have been scored. It states that `` the use of GLT must be stipulated in the respective competition rules ''. The Laws themselves are not specific as to the nature of Goal Line technology systems, however other documentation from FIFA, which is cited by the Laws, goes into more detail. The FIFA Quality Programme for GLT Testing Manual precisely define the requirements of the systems. Four basic requirements of a system are stipulated : The system must address only the matter of whether a goal has been scored or not. The system must be accurate. The system must indicate the scoring of a goal immediately, confirming this within one second. The system must communicate its information solely to the match officials ( via vibration and visual alert on the referee 's watch ) FIFA have a system whereby a particular technology provider needs to show effectiveness to successfully obtain a license for their technology, then an installation within a particular stadium must pass a `` final installation test '' before use, and before each game the referee must check that the system is functional. Current implementation Due to the expense of goal - line technology systems, the technology is only currently used at the very top levels of the game. In domestic competition, goal - line technology is only regularly used in a few major European leagues : Serie A, Ligue 1, the Bundesliga, and the Premier League. As of January 2018, FIFA 's website list 144 stadiums with licensed GLT installations, all of which use the Hawk - Eye system. GoalControl is also licensed for use, but is not currently installed in any stadium History Pre-implementation history Prior to 2012, competitions were unable to implement technology as provision was not made for it in the Laws. The Laws of association football are controlled by the International Football Association Board ( IFAB ), a body on which FIFA holds 50 % of the voting power, sufficient to veto any changes to the laws. Pre-2011 Compared to other sports, association football was late to allow technology to assist with in - game decisions. The matter was a subject of debate within the game for over a decade with the game 's lawmakers resisting calls for its implementation. Throughout the 2000s various incidents incited discussion as to the potential for goal - line technology in the game. The lack of use of technology in association football was contrasted with other sports, which had incorporated video replays and other systems into their rules. In response to this, FIFA decided to test a system by Adidas in which a football with an embedded microchip would send a signal to the referee if it crossed a sensor going through the goal. According to FIFA president Sepp Blatter, `` We did different tests at the Under - 17 World Cup in Peru but the evidence was n't clear so we will carry out trials in junior competitions in 2007 ''. However, those trials did not materialise and by 2008, Blatter had rejected the system outright, describing the technology as ' only 95 % accurate '. FIFA and IFAB were resistant to introducing technology in the game, voting in March 2010 to permanently ditch the technology. Following several refereeing errors at the 2010 FIFA World Cup -- including the disallowed goal in Germany 's 4 -- 1 victory over England, when Frank Lampard hit a shot from outside of the penalty box that bounced off the crossbar and over the line ; the ball came back out and the goal was disallowed because the assistant referee did not call for a goal -- Blatter announced that FIFA would reopen the goal - line technology discussion. Before Euro 2012, UEFA president Michel Platini dismissed the need for goal - line technology, instead arguing for placing additional assistant referees behind the goal. However, in a Group D match with Ukraine losing 1 -- 0 to England, the on - field officials did not see Ukraine 's Marko Dević 's shot briefly cross the line before it was cleared by England 's John Terry, although an offside in the build - up to the incident was too unnoticed by the match officials. Initial testing The Adidas Teamgeist II with implanted chip, part of the proposed Cairos - Adidas system for goal - line technology Heeding calls for the use of technology, in July 2011 FIFA began a process of sanctioned tests that eventually resulted in the approval of the systems used in the current game. The first stage of testing considered multiple goal - line technology systems, with the requirement that the system notified the referee of the decision within one second of the incident happening. The message needed to be relayed via a visual signal and vibration. Tests were conducted by Empa between September and December 2011. Tested systems included : A system from Carios Technologies, in collaboration with Adidas based around a modified ball with an implanted chip, and a magnetic field generated by thin cables behind the goal line. The system could detect if the ball passed through the field. GoalRef : Another system based on generated magnetic fields and a sensor within the ball. Goalminder : A system based on cameras installed in the goal frame. This provided a visual playback to officials rather than an automatic goal - or - no - goal alert. Hawk - Eye : A Sony - owned system based several on multiple high - speed cameras whose images are used to which triangulate the position of the ball. Hawk - Eye systems were, and still are, used in several other sports for supporting officiating decisions. Second phase of testing On 3 March 2012, IFAB announced that two of the eight proposed systems had proceeded to the second stage of testing. These were Hawk - Eye and GoalRef. In the second phase of testing, the manufacturer of the technology chose a stadium to test its technology in a number of imagined scenarios. Testing was also conducted in professional training sessions and in laboratories to account for different climatic conditions and other magnetic field distortions. Tests on the watch to be worn by referees were also be undertaken. The systems also each underwent testing in some competitive matches. GoalRef technology underwent match testing in some Danish Superliga matches in the first half of 2012. Following the second phase trials, on 5 July 2012 IFAB approved GoalRef in principle, making it available for use in professional matches under a set of revised Laws of the Game. Each installation however would also require licensing approval for use in the individual stadium, on a 12 - month basis. The 2012 FIFA Club World Cup was the first tournament where GoalRef was used by a match referee. Goal Ref was used for the first time on 6 December 2012 in the first match of the 2012 FIFA Club World Cup. The first match to use the Hawk - Eye goal - line technology was Eastleigh F.C. versus A.F.C. Totton in the Hampshire Senior Cup final at St Mary 's Stadium, Southampton in England on 16 May 2012. Although it used Hawk - Eye, the system had no bearing on the referee 's decisions and the system readings were only available to FIFA 's independent testing agency. The system was also in place for the technology 's second test on 2 June for England 's friendly match against Belgium. Introduction Edin Džeko of Manchester City scored the first goal in the Premier League that was given by goal - line technology Following the success of the trials, in July 2012 IFAB voted unanimously to officially amend the Laws of the Game to permit ( but not require ) goal - line technology. In December 2012, FIFA announced it would introduce goal - line technology at the 2012 FIFA Club World Cup in Japan. Hawk - Eye technology was employed at Toyota Stadium, while GoalRef was used at International Stadium Yokohama. GoalControl, a camera - based system which uses 14 high - speed cameras located around the pitch and directed at both goals, was used at 2013 Confederations Cup, partly as a trial for use at the next year 's World Cup. The Football Association announced that Hawk - Eye would be used in the 2013 -- 14 Premier League season. On 16 December 2013, it was announced that Hawk - Eye would be used in three of the four quarter - finals and any subsequent matches in the League Cup. The system was used when, on the very next day, in the Sunderland -- Chelsea quarter - final, a goal from Frank Lampard was allowed. The first goal to be decisively awarded using goal - line technology in the English Premier League was Edin Džeko 's goal for Manchester City against Cardiff City on 18 January 2014. Following success at the Confederations Cup, GoalControl was used at the 2014 FIFA World Cup. The first goal given by the technology was in the 15 June 2014 group stage match between France and Honduras. Goal Line Technology was implemented across the major European competitions. In December 2014, the Bundesliga clubs approved goal - line technology that will be introduced at the start of the 2015 -- 16 Bundesliga season. The league picked the cheaper Hawk - Eye system over two German technologies. GoalControl was introduced for Ligue 1 for the start of the 2015 -- 16 Ligue 1 season. Ligue 1 later switched to using Hawk - Eye in 2018 after the GoalControl system made errors. Goal Line Technology was used in the UEFA Europa League final, UEFA Champions League, European Championship and Copa America for the first time in 2016. Criticism Human element is lost While advocates for goal - line technology maintain that it would significantly reduce refereeing errors during play, there are also criticisms of the technology. Much of the criticism came from within FIFA itself including former FIFA president Sepp Blatter. Apart from the criticisms revolving around the technical aspects of the two proposed technologies, critics point out that such technology would impact on the human element of the game and remove the enjoyment of debating mistakes. Sepp Blatter has been quoted as saying `` Other sports regularly change the laws of the game to react to the new technology... We do n't do it and this makes the fascination and the popularity of football ''. A study suggested that in the 2010 -- 11 Premier League season `` errors took place nearly 30 % of the time that video replays could help prevent '', but some people claim that instant replays would interrupt the flow of the game and take away possible plays. Other critics believe it would be prohibitively expensive to implement the technology at all levels of the game and particularly for smaller / poorer football associations. FIFA officials have expressed a preference for ' better refereeing ' as well as more match officials over implementing the technology. Advocates in turn cite the many examples of incorrect goal - line decisions deciding important games and point out that the technology has improved much since the initial trials carried out by FIFA. Advocates contend that any extra help for the referee should outweigh arguments that it would lead to non-uniform rules ( since not all football associations would be able to implement it ). Blatter had been opposed to goal - line technology until Frank Lampard 's disallowed goal in the 2010 World Cup where the ball clearly crossed the line. The introduction of additional assistant referees, who are mostly positioned beside the goal - line, was partly in order to facilitate in such situations. Cost In April 2013, MLS commissioner Don Garber confirmed that MLS would not adopt goal - line technology for the 2014 season, citing cost as the overriding factor. GoalControl installation would cost about $260,000 per stadium, and a further $3,900 for each game. In early 2014, the vast majority of teams in the two divisions of the German Bundesliga voted against introducing goal - line technology for financial reasons. The costs per club would have ranged from € 250,000 for a chip inside the ball up to € 500,000 for Hawk - Eye or GoalControl. The manager of 1. FC Köln, Jörg Schmadtke, summarized the vote with `` The cost is so exorbitant, that using this ( technology ) is not acceptable ''. World governing body FIFA are set to make £ 300,000 from the Premier League 's decision to install goal - line technology in all top - flight stadiums before the start of next season. Each of the 20 clubs will have to pay FIFA £ 15,000 to install, test and receive the ' FIFA quality seal ' for Hawk - Eye 's camera - based system, which is expected to cost around £ 250,000 per ground in total. FIFA will also make an extra £ 15,000 from Wembley Stadium, which will have the technology installed for use in events such as the FA Cup semi-finals and final. The Scottish Professional Football League stated in December 2017 that it would not be implementing goal - line technology, as it is only affordable for the richest leagues in Europe.

Question: when was goal line technology first introduced in the premier league
Answer: the 2013–14 Premier League season
