Founding and incorporation

Apple was established on April 1, 1976 by Steve Jobs, Steve Wozniak and Ronald Wayne to sell the Apple I personal computer kit.

 The kits were hand-built by Wozniak and first shown to the public at the Homebrew Computer Club. The Apple I was sold as amotherboard (with CPU, RAM, and basic textual-video chips), which is less than what is today considered a complete personal computer.The Apple I went on sale in July 1976 and was market-priced at $666.66 ($2,723 in 2012 dollars, adjusted for inflation.)

Apple was incorporated January 3, 1977 without Wayne, who sold his share of the company back to Jobs and Wozniak for $800. Multi-millionaire Mike Markkula provided essential business expertise and funding of $250,000 during the incorporation of Apple.

The Apple II was introduced on April 16, 1977 at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 andCommodore PET, due to its character cell-based color graphics and an open architecture. While early models used ordinary cassette tapes as storage devices, they were superseded by the introduction of a 5 1/4 inch floppy disk drive and interface, the Disk II.

The Apple II was chosen to be the desktop platform for the first "killer app" of the business world, VisiCalc, a spreadsheet program. VisiCalc created a business market for the Apple II and gave home users compatibility with the office, an additional reason to buy an Apple II. Apple was a distant third place to Commodore and Tandy until VisiCalc came along.

By the end of the 1970s, Apple had a staff of computer designers and a production line. The company introduced the ill-fated Apple III in May 1980 in an attempt to compete with IBM and Microsoft in the business and corporate computing market.

Jobs and several Apple employees including Jef Raskin visited Xerox PARC in December 1979 to see the Xerox Alto. Xerox granted Apple engineers three days of access to the PARC facilities in return for the option to buy 100,000 shares (800,000 split-adjusted shares) of Apple at the pre-IPO price of $10 a share.Jobs was immediately convinced that all future computers would use a graphical user interface (GUI), and development of a GUI began for the Apple Lisa.

On December 12, 1980, Apple went public at $22 per share, generating more capital than any IPO since Ford Motor Company in 1956 and instantly creating more millionaires (about 300) than any company in history.
