culture in much of small-town America. Football is a major source of revenue to the athletic programs of schools, public and private, in the United States. The top college football players enter the NFL Draft after their college careers are over, in hopes of signing with an NFL team. "FBS" and "FCS" are abbreviations for the Football Bowl Subdivision and Football Championship Subdivision, two sections of Division I that exist only in football. These two subdivisions were formerly known as Divisions I-A and I-AA respectively. The Championship Subdivision, consisting mostly of smaller schools than the FBS but larger than D-II, has a multiple-round playoff system just like Divisions II and III, while the Bowl Subdivision has only a limited, and unofficial, four-team playoff and has historically only featured division championships and bowl games. FBS and FCS teams can, and often do, play against each other. Unofficially, the Bowl Subdivision is divided into two further subdivisions, "major conferences" (also known as "Power Five conferences") and "mid-majors" (known in modern parlance as the "Group of Five"). In practice, only major conference teams are eligible to compete for the national championship and receive significant favor in the opinion polling over mid-majors, and it was not until the addition of the BCS National Championship Game that mid-majors had a realistic chance at appearing in one of the major bowls. Although the FCS has a playoff, three conferences do not participate (the Ivy League does not allow its teams to play in the postseason, and the historically black SWAC and MEAC instead play each other in a bowl of their own). Division III teams do not offer scholarships to their players; two Division I FCS leagues also do not offer scholarships—the Ivy League, which prohibits athletic scholarships in any sport, and the Pioneer Football League, which only competes in football and whose members all offer scholarships in non-football sports. With the exception of the annual Army–Navy Game, only Power Five conference teams air on national broadcast television, although mid-majors, FCS teams, D-II and D-III games can see more limited coverage on cable and local television. Though the NCAA is the most publicized college athletic organization, the NAIA (which houses mostly smaller private colleges in the midwest), NJCAA (an association for community colleges), and California Community College Athletic Association (CCCAA) (that state's equivalent to the NJCAA) also sanction football games; there also exists a club football
