Adidas introduced Footballitis, a fictitious fever affecting football fans worldwide, as the concept for its FIFA World Cup 2002 campaign. The symptoms of the condition were revealed in three stages, over a six-month period: Fever, Mania and Footballitis.Our aim was to raise the standard of Internet sports marketing by offering visitors an unparalleled degree of interaction with the online environment. Our goal was to fully-integrate the online component of the campaign into Adidas' overall World Cup communication.Our brief was to create individual online campaigns for each stage, beginning with the Adidas Fevernova match ball and continuing with the launch of the new Predator Mania boot. The Predator Mania microsite introduced the boot, and aimed to increase the number of users registered to adidas.com.The microsite launched the Predator Mania Simulator, an online game inviting players to perfect their goal-scoring skills using play mechanics more complex than those of the Fever Stage's Fevernova Simulator. Each week, the most-skilled players qualified to win a pair of Predator Mania boots. The microsite also featured interactive demonstrations of the Predator Mania boot, the evolution of Adidas boot technology and the Adidas Federation Kits.The Predator Mania microsite continued the success of the Fevernova microsite, with new user registrations to adidas.com exceeding overall forecasts within the first two months of the six-month Footballitis campaign.
