BioProject: Team Ownership Histories

The SABR Team Ownership Histories Project is a joint effort of SABR’s Business of Baseball Committee and the BioProject. These essays aim to provide as much detail as possible about the organization and composition of ownership groups, franchise sales, relocations, stadiums, and other issues that provide the financial context for team success on the field.

The project has been expanded to include teams from the All-American Girls Professional Baseball League, the Negro Leagues, and the Federal League, as well as defunct 19th-century teams from the American Association, National Association, National League, and Union Association, an expansion pioneered by Charlie Bevis.

Thanks to Len Levin for his work in copy editing all of these essays.
