when was goal line technology introduced in football
Goal-line technology 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[3][4] and 2015 Women's FIFA World Cups.[5]
Field goal The longest field goal kick in NFL history is 64 yards, a record set by Matt Prater on December 8, 2013. The previous record was 63, originally set by Tom Dempsey and then matched by Jason Elam, Sebastian Janikowski, and David Akers. High school, college and most professional football leagues offer only a three-point field goal; however, some professional leagues have encouraged more rare kicks through four-point field goals. NFL Europe encouraged long field goals of 50 yards or more by making those worth four points instead of three (much like Australian rules' Super Goal or basketball's three-point line), a rule since adopted by the Stars Football League. Similarly, the sport of arena football sought (unsuccessfully) to repopularize the drop kick by making that worth four points; it failed, since only one kicker (Brian Mitchell) was able to do it with any semblance of proficiency. (In six-man football, where there is no offensive line, all field goals are worth four points instead of the usual three.)
