In addition to racial prejudice, economic and other complicated factors contributed to segregation in baseball. For example, many owners of major league teams rented their stadiums to Negro League ones when their ownwere on the road, and team owners knew that if baseball were integrated, the Negro Leagues would probably not survive, losing their best players to the majors, and Major League owners would lose significant rental revenue, and many Negro League players would lose their livelihoods. The Negro National League disbanded after the the 1949 season, although the Negro American League continued throughout the the 1950s, though the quality of play petered out regularly as black baseball's best talent was carried off by the Major and Minor Leagues.
