inform us why the NFL is a tax exempt entity, since they clearly don't appear to be a non-for-profit company.

The NFL is a huge corporation that makes billions of dollars of a sport and television rights. The sports industry should not be considered a non-for-profit when in fact their main goal is to produce a product that the consumer wants and willing to spend money on to enjoy. They profit from the American public and avoid taxes due to their tax exemption status. This needs to be revoked and inject our economy with the millions of dollars of tax revenue to the public.
