A Wired.com article says "there are murmurs of a high-profile Super Bowl ad to pay homage to the "1984" ad by Ridley Scott that launched the Mac. The influential ad, which cost a fortune and was shown only once, has become one of the most famous and celebrated spots in advertising history."

Apple is talking to its agency, TBWA/Chiat/Day, about an anniversary ad that would be "reminiscent" of the original, according to a December article in Advertising Age.
Details weren't leaked, but the magazine suggested the company thought about rerunning the original ad to save money, but decided against it because no one under 45 or so would get it.
A spokesman for TBWA/Chiat/Day said he couldn't talk about it. "We'd have to get permission from Apple," he said, in a tacit admission that something is up.
Whether or not Apple runs a tribute spot, the company will have a Super Bowl presence thanks to Pepsi, which has teamed with Apple in a bottle-cap promotion to give away 100 million songs through the iTunes Music Store.
