I think the reason why WWE doesn't get NASCAR money is because TV execs, aswell as advertisers view wrestling fans as low-IQ'd, no money having trailer trash even lower than NASCAR fans. Attitude Era was very lucrative for WWE, but it sure gave them such a stigma they are still trying to wash off, not even from the content, but from the fans it brought in. This is why UFC doesn't get real major sponsors, they got those old Attitue Era fans.
