Professional sports today have very high stakes. There is an enormous amount of money and prestige involved and
a huge effort goes into preparing for competitions at the highest levels. Fans also expect a lot from their teams and every move and every performance is closely scrutinised.
In this environment there is a great need to ensure that close decisions are correctly called and the results are fair and reflect the actual performance on the field.
Referees are human and sometimes make wrong decisions either because they did not spot the action accurately or missed it completely. As a result, fouls go unnoticed or legitimate goals get disallowed because of the absence of goal-line technology. How often do you see players vehemently protesting a decision because they have seen something the referee hasn’t? 
Technologies like Hawk-Eye track the ball’s trajectory and can help officials make accurate decisions. Hawk-Eye technology is used very effectively in cricket and tennis and fans and players have both been quite receptive to it. Technology in football can also play a big role.
There are also several options available for goal line technology and many of them have also been evaluated. TV viewers are able to watch replays using these technologies and can tell when a wrong decision has been made.
