We are two days away from Super Bowl 50, which will be the first Super Bowl not designated by a Roman numeral. Fifty in Roman numerals is "L," and "L" is also a symbol that has come to mean "loser." The NFL will resume using Roman numerals for Super Bowl LI.
Despite this being Super Bowl 50, it is only the 48th game dubbed as the "Super Bowl." The first two were called "The AFL-NFL World Championship," and were later known as Super Bowls I and II.
