The correct answer is...Reebok.

Indeed, the official sponsor for 1996 Olympics was Reebok not Nike!!

Atlanta entered the Olympic bidding in 1988, in a fierce competition with Athens to get the title 'Host city for Summer Olympic 1996'. Atlanta is also known for the home of Coca-Cola company headquarters. Although, it is always said that cities win on the basis on their bid and the facilities they can offer for the athletes, spectators, media etc., some people thought that the headquarters of Coca-cola might have been an influential factor in the choice of Atlanta.
The Atlanta bid was initiated by Atlanta lawyer Billy Payne and this decision had a big effect on the community. Thousands of people were inspired by one man's vision to bring the Games to the city. But the event is claimed to be an entirely a privet-sector phenomenon, meaning that without the usual finance from the government. It is said that The International Olympic Committee got sold out for money and everything has a cost. There was a lot of bad coverage from media when the Games were happening and also rules and regulations were not in place.

However, the game has been memorable and later reported that the crows have been the largest in Olympic history.

This is how it happened: Nike managed to build a Nike village next to the athletes village with a massive logo on display. Also it bought a significant amount of billboard space around the venue to promote the brand.

A research was conducted with 1,512 people being interviews in the Olympic Park, Atlanta before and during the sixteen days of the Olympic Games(July-August 1996) to measure the performance of the Olympic sponsors. And these are the result:

Coca-cola managed it well, because 83% of people recalled it as an official sponsor. However, Nike(22%) was remembered more in the Media than the official sponsor Reebok( 16%). In the same game Samsung played some ambush marketing tricks and got 9% of the attention, whereas the official sponsor Panasonic received only 3% of coverage.
