Most Big Ten fans had little reason to pay attention to the league's Council of Presidents/Chancellors before December 2009.
But once the expansion process began, the COP/C entered the spotlight and has made several historic decisions in the past year and a half.
The Big Ten on Thursday announced its COP/C executive committee for the 2011-12 academic year.
Indiana president Michael McRobbie will serve as chair for the second year of his term.
Iowa president Sally Mason will serve as vice chair.
Michigan State president Lou Anna K. Simon and Penn State president Graham Spanier will serve on the executive committee. Simon was COP/C chair when the Big Ten approved Nebraska for admission last June.
The COP/C, which meets twice a year -- usually in June and December -- has the "ultimate authority and responsibility in Big Ten Conference governance," according to a news release. Each chair serves a two-year term.
