When did the third umpire first make its appearance in cricket?

The third umpire debited in Test Cricket at Kingsmead, Durban for the South Africa Vs India series in 1992/93. Sachin Tendulkar became the first man to be dismissed (run out) by television replays. If the field umpires are unable to accurately come to decision on the dismissal of a batsman, the umpire requests the third umpire to ascertain whether the batsman had made it home. The third umpire then looks at various TV replays from different angles, and comes to a conclusion by pressing the appropriate signal. Originally decisions wee conveyed in traffic light style (a red light indicating a batsman’s dismissal, a green light not out) but it is now common practice to display the decision via the big screen scoreboard.
