How we’re counting this“First computer program” is too broad; this refers specifically to the first electronic stored program run on a computer.
How do you count “winning it all”?

We count the top championship named for the selected competition—not conference, division, playoff appearance, or consolation titles. Season labels stay separate from the date the trophy was actually clinched.

  • NFL defaults to Super Bowls; pre-Super Bowl league titles are identified separately when included.
  • Relocations follow the franchise unless a league’s official record book separates the history.
  • FBS selectors, split titles, claims, vacancies, and co-champions are labeled rather than flattened.
