Temple University, which began playing football in 1894, fields the only Division I FBS football team in the Delaware Valley. Temple, one of many schools that switched conferences in the early 2010s, joined the Big East Conference in 2012; when the Big East split a year later, Temple moved its entire athletic program to the Big East's football-sponsoring successor, the American Athletic Conference. Although Temple is the lone FBS school in the region, the Pennsylvania State University Nittany Lions are the most popular college football team in Philadelphia and the Delaware Valley. Penn State is a member of the Big Ten, one of the "Power Five conferences" in college football. The school began playing football in 1887, and has won two consensus national championships. Many fans in the Philadelphia area also root for the Atlantic Coast Conference-affiliated University of Notre Dame Fighting Irish or the Big Ten-affiliated Rutgers Scarlet Knights.
