What is the Roman numeral for Super Bowl 2025? SB LIX explained, history, how it works
The use of Roman numerals did not become an NFL tradition until Super Bowl V in 1971. The first two Super Bowls were known as the AFL-NFL world Championship Game. The name “Super Bowl” was officially adopted for the third annual game and the league retroactively added Roman numerals to the Super Bowls before 1971.
