The phrase “March Madness” and the NCAA tournament each have slightly different “creators,” so the answer depends on what you mean by “who made March Madness.”

Short answer

  • The NCAA men’s basketball tournament itself was created in 1939, largely pushed by Ohio State coach Harold Olsen and the NCAA basketball committee as a national alternative to the NIT.
  • The phrase “March Madness” was first used for basketball by Illinois high school official Henry V. Porter in 1939, talking about the Illinois high school tournament.
  • The phrase became linked to the NCAA tournament when CBS broadcaster Brent Musburger used “March Madness” on-air during the 1982 men’s tournament.

Who “made” the tournament?

In the late 1930s, New York’s National Invitation Tournament (NIT) was the main postseason college basketball event, run by sportswriters and centered in Madison Square Garden.

Harold Olsen, then Ohio State’s coach and chair of the NCAA Basketball Committee, wanted a truly national championship tournament not dominated by New York interests.

  • In 1939, the first NCAA men’s basketball tournament tipped off with just eight teams.
  • Oregon beat Ohio State to win that first title, in what we now retroactively call the first “March Madness.”

So if you mean “who made the March Madness tournament exist at all,” Harold Olsen and the NCAA basketball committee are usually credited as the key movers.

Who coined “March Madness”?

The term didn’t start with the NCAA or TV networks.

  • In 1939 , Illinois high school official Henry V. Porter used “March Madness” in writing about the frenzy of the Illinois state high school basketball tournament.
  • For decades, the term mainly belonged to Illinois high school basketball , not the college game.

Because of that history, when the phrase later became big money around the NCAA tournament, there were legal disputes between the NCAA and the Illinois High School Association (IHSA) over who owned the name.

How did “March Madness” get attached to the NCAA tourney?

The phrase really became national when TV got involved.

  • In 1982 , CBS broadcaster Brent Musburger , who had covered Illinois high school hoops earlier in his career, used “March Madness” during coverage of the NCAA men’s tournament.
  • The phrase caught on with viewers, networks, and advertisers, and soon it became the brand name for the NCAA Division I men’s basketball tournament.
  • By the late 1980s and 1990s, the NCAA was licensing and protecting “March Madness” as a commercial property, eventually reaching huge TV deals (like the multibillion‑dollar CBS/Turner contract).

So if you mean “who made March Madness into the thing everyone calls the NCAA tournament,” Brent Musburger is the broadcaster most often credited.

What about brackets and betting?

Another part of “who made March Madness” is the culture of brackets and office pools.

  • The single-elimination bracket format (easy to print on one sheet of paper) helped turn the tournament into a national office‑pool obsession.
  • Stories trace early organized bracket pools to things like a Staten Island bar’s Final Four pool in the late 1970s and a Kentucky postal worker adapting a softball bracket idea for the 1978 NCAA tournament, though there’s no single universally accepted “inventor” of the bracket pool.

This bracket culture is a big reason people feel like “March Madness” is more than just a set of games.

Today’s meaning of “March Madness”

Now, March Madness usually refers to:

  • The NCAA Division I men’s basketball tournament (and increasingly the women’s tournament too).
  • A three‑week national event built around upsets, Cinderella teams, and bracket predictions.

In short:

  • Harold Olsen + NCAA → created the national tournament (1939).
  • Henry V. Porter → coined “March Madness” for high school hoops (1939).
  • Brent Musburger → made “March Madness” the nickname for the NCAA tournament (1982).
