Setting the scene
Hungarian architecture professor Ernő Rubik invented his twistable cube in 1974 and called it the Magic Cube; it spread through Hungarian toy fairs before Western companies noticed its obsessive appeal. By the late 1970s, Ideal Toy Corporation negotiated rights to sell it outside Hungary, renaming it the Rubik's Cube for global markets.
What happened
In 1980 the puzzle was licensed internationally and launched in the United States and Europe, priced around $1.99 and marketed as a brain teaser for all ages. Within two years it sold more than 100 million units worldwide, spawned books of algorithms, and triggered a craze of speed competitions and bedroom record attempts.
Why it still matters
The cube outlived fad status to become a permanent fixture of toy stores, mathematics classrooms, and competitive sport governed by the World Cube Association. Memorable detail: the classic 3×3×3 cube has 43,252,003,274,489,856,000 possible arrangements, yet every scrambled state can be solved in twenty moves or fewer.
Background
Speedcubing communities later broke world records.
