When the Super Bowl started in 1967, the game was played in January but belonged to the previous season. Calling it "the 1966 championship played in 1967" was confusing.

Man tror romertall stammer fra håndsignaler og tellemerker. Streken I representerer en finger, V representerer åpningen mellom tommel og fingre for fem, og X representerer kryssede hender for ti. Bokstavene L, C, D og M kommer fra modifikasjoner av greske bokstaver som chi, theta og phi for å representere 50, 100, 500 og 1 000. Over tid ble disse merkene til de latinske bokstavene folk kjenner igjen i dag. Det finnes ingen 0 i det romerske alfabetet, ettersom konseptet for tallet 0 ikke ble fullt utviklet før India oppfant det rundt 600 e.Kr. / 10600 HE.
