 The IRFU was renamed the Eastern Football Conference in 1960, while the WIFU was renamed the Western Football Conference in 1961.Also in 1961, limited intersectional play was introduced.Because the West played 16 games by this time while the East still only played 14, this arrangement oddly allowed both the four-team Eastern Conference and the five-team Western Conference to play three games per intraconference opponent and one game per interconference opponent.
