NFL introduces Instant Replay technology
1999 Rules of Replay
Coaches challenge: Outside the final two minutes of each half, each team will be permitted two challenges per game that will initiate referee reviews. Each challenge will cost a team a time-out. If a challenge is upheld, the time-out will be restored, but the challenge will not. No challenges will be recognized from a team that has exhausted its time-outs.

Final two minutes of each half: After the two-minute warning of each half, and throughout any overtime period, any referee review will be initiated by the replay assistant in the replay booth in the press box. He can initiate as many review requests as he thinks necessary, no matter how many time-outs the teams may have. No time-out will be charged for a review initiated from the replay booth.

Referee review: All replay reviews will be conducted by the referee on a field-level monitor after consultation with the other covering officials on the play. A decision will be reversed only when the referee has indisputable visual evidence that the call should be changed. The referee cannot initiate a replay in any instance.

Time limit: Reviews will be a maximum of 90 seconds, timed from when the referee puts on the head phones to the replay booth.

Reviewable plays: The instant replay system will cover a variety of plays in three main areas — 1) sideline, goal line, end zone, and end-line plays; 2) passing plays; and 3) other detectable infractions, such as a runner ruled down not by defensive contact, and the number of players on the field.
