Basketball shoes are hot and Nike controls the sizzle .

The World Cup is a rare opportunity to market products to the entire world.

Sales of basketball shoes hit $3.7 billion dollars last year. A look back at two athletes' endorsement deals that changed the industry.

Athletes are no strangers to controversy, posing dilemmas for corporate sponsors. Pistorius is the latest challenge for Nike, whose problem children have included Lance Armstrong, Tiger Woods and NFL quarterback Michael Vick.

The Lance Armstrong Foundation has rebranded itself as Livestrong, so the cyclist's doping scandal may well have little if any effect on the organization he founded to help cancer patients.

Nike announced this morning it has severed its endorsement deal with Lance Armstrong. The cyclist also says he is stepping down as chair of the Livestrong cancer charity he founded.

Until this morning the daycare facility at Nike headquarters near Beaverton, Ore., was officially called the Joe Paterno Child Development Center.

The new track and field uniforms for this year's Olympic games were recently unveiled by Nike.

In one week, the NFL will start selling apparel made by Nike rather than Reebok. The sports body is trying to capitalize on the switchover.
