Description:
Baseball is known as America's pastime, but football is woven into the country's love of sports. The NFL's rise came at the same time as television's and turned into a $9 billion enterprise. The NFL season has far fewer games than the other major North American sports — 16 compared to 162 in baseball — which makes every game an event.
