How did the Elite Eight get its name?

“Elite Eight” was originally coined by the Illinois High School Boys Basketball Championship, the single-elimination tournament run by the Illinois High School Association. In 1956, the field was reduced from 16 teams to eight, and the phrase “Elite Eight” was born.

The trademark rights are now held by the March Madness Athletic Association, a joint venture between the NCAA and IHSA formed in 1996. (via IHSA)
