This was the first awards show in history to use a computer-generated graphic timer clock to notify awardees how much time they had to give their speeches before time was up. The countdown clock was displayed on a large screen TV in front of the stage. It was controlled by the assistant director who had the discretion to activate it or not depending on the importance of the award and, for this show, was programmed for 30 seconds. This has since become a staple element of almost all award shows and is often followed up by the music when the awardee ignores the clock.
