The last time there was a World Cup, in 2010, Adidas saw its football business jump 14 percent.
Nike, which entered the market in 1994, had football-related sales of $1.9 billion last year, putting the company right on Adidas' heels. Nike quickly increased its profile by sponsoring the kits for such teams as Barcelona and Manchester United. Last month, the Oregon-based company revealed the World Cup kits for the hometown Brazilian team.
Adidas founder Adi Dassler made the company's first pair of football cleats in 1925 in Herzogenaurach, Germany. As legend has it, Dassler helped West Germany beat the mighty Hungarians in the 1954 World Cup because of shoes he designed with screw-in studs that aided traction on the rain-slicked pitch.
In the lead-in to the World Cup, Adidas has introduced four Samba football boots: the blue Adizero F50, the berry-colored Predator, the "slime" green Nitrocharge and the purple 11Pro. The colors were chosen to pay tribute to Carnival.
The company also updated the kits for many of its national teams, including Spain, Argentina, Germany and Colombia.
But the ball is what brings the most buzz. Designers have been sworn to secrecy and those who have been allowed to see the ball had to sign a confidentiality agreement.
A contest was held in Brazil to name the ball, and the Brazuca an informal word often used to describe national pride in the South American nation was born, beating out fellow finalists Bossa Nova and Carnavalesca.
The 2010 World Cup match ball was called Jubulani and was made of eight thermally bonded panels. Adidas sold 13 million of them.
To mark the introduction of the Brazuca which will have its own Twitter account Adidas says that parents of every baby born in Brazil on Tuesday will be entitled to receive a ball next Friday and Saturday at specific locations in all 12 host cities. They will need to present the child's birth certificate as proof.
Adidas and FIFA recently agreed to extend the company's agreement to make the World Cup ball to 2030. The value was not disclosed, though FIFA top-tier sponsorships are currently estimated at about $100 million per four-year World Cup cycle.
"Adidas was built on soccer," said Antonio Zea, the company's innovation director for football. "It's part of our DNA."
