The Hall used the BBWAA's Historical Overview Committee to formulate the ballots for each era, consisting of 12 individuals for the Expansion Era and 10 for the other eras. The Hall's board of directors selected a committee of 16 voters for each era, made up of Hall of Famers, executives, baseball historians, and media members. Each committee met and voted at the Baseball Winter Meetings once every three years. The Expansion Era committee held its first vote in 2010 for 2011 induction, with longtime general manager Pat Gillick becoming the first individual elected under the new procedure. The Golden Era committee voted in 2011 for the induction class of 2012, with Ron Santo becoming the first player elected under the new procedure. The Pre-Integration Era committee voted in 2012 for the induction class of 2013, electing three figures. Subsequent elections rotated among the three committees in that order through the 2016 election .
