Instant Replay is an immediate playback of any incident that is either shot or broadcasted live. Tony Verna gave the idea for the device in the 1960s. Instant replay slowly became more pervasive in the sports world. Initially, the technique was not adopted by Leagues' umpires and officials. However, it was employed by the teams to improve the in-stadium experience for fans and also for the sportspersons in improving their performances by observing the flaws that happened while playing.
