The concept for the Soccer Bowl began in 1975 by then NASL Commissioner Phil Woosnam, who was trying to build a neutral-site championship event in the mold of the NFL's Super Bowl. Unlike the Super Bowl, the annual numbering scheme of the match did not use Roman numerals (e.g., Super Bowl XXI) but instead used the last two digits of the year played (e.g., Soccer Bowl '78). The original NASL's last Soccer Bowl took place in early October 1984 in a best-of-three series, as the league ceased operation in 1985.
