Apple turns 50 — one of the world's biggest tech companies started with hobbyist computers

Apple is 50 years old.

Founded in 1976 as a partnership between Steve Jobs, Steve Wozniak, and Ronald Wayne.

Officially incorporated in Cupertino, California, in January 1977.

Early products included the Apple-1, designed by Wozniak with only about 200 units made, and the Apple II, which brought computers to the masses and used a television as its screen.

The Apple II's popularity was boosted by VisiCalc, an early spreadsheet program.
