As of right now, Notre Dame still holds the highest TV ratings. Like them or hate them, people tune in to watch them. As of last year, they were followed in no particular order by: Penn State, Alabama, Ohio State, Texas, Nebraska and Michigan. I believe Penn State was second but I do not know the following order.
Notre Dame has their own TV contract, Penn State benefits from being prior inependent which gained them a National TV following before they joined the Big Ten. The rest are traditional powers also which brings in big TV ratings.
So Notre Dame, followed by Penn State, Alabama, Ohio State, Texas, Nebraska, and Michigan.
EDIT: This answer is incorrect, ND had a 2.92 average ranking last year on TV, Nebraska alone had a 3.57. I'm not sure who has the highest, but it's not ND.

The Arkansas Razorbacks from the University of Arkansas are the most successful Arkansas football team. Arkansas does not have a National Football team, therefore the most successful team would be a college team.
