This system has been challenged often, beginning with an NCAA committee proposal in 1979 to have a four-team playoff following the bowl games. However, little headway was made in instituting a playoff tournament until 2014, given the entrenched vested economic interests in the various bowls. Although the NCAA publishes lists of claimed FBS-level national champions in its official publications, it has never recognized an official FBS national championship; this policy continues even after the establishment of the College Football Playoff (which is not directly run by the NCAA) in 2014. As a result, the official Division I National Champion is the winner of the Football Championship Subdivision, as it is the highest level of football with an NCAA-administered championship tournament. (This also means that FBS student-athletes are the only NCAA athletes who are ineligible for the Elite 90 Award, an academic award presented to the upper class player with the highest grade-point average among the teams that advance to the championship final site.)
