Nascar Used Here

Including ticket sales, television contracts, merchandising, advertising, partnerships etc.. Basically, I am trying to look at the "big picture" here. I want to know which makes more money, in total, the NFL and it's teams, or NASCAR and all it's teams. The answer is not just one aspect of sales (eg ticket sales), rather I would like to know which one makes more in total... to use an analogy---think of the answer in terms of the United States GDP... what's the GDP of NFL vs. NASCAR???
