John Sculley

April 10, 1985: During a fateful meeting, Apple CEO John Sculley threatens to resign unless the company’s board of directors removes Steve Jobs as executive VP and general manager of the Macintosh division.

This triggers a series of events that will ultimately result in Jobs’ exit. The marathon board meeting — which continued for several hours the next day — results in Jobs losing his operating role within the company, but being allowed to stay on as chairman. Things don’t exactly play out like that.

April 8, 1983: John Sculley, former president of PepsiCo, takes charge as Apple’s third CEO.

Despite a total lack of experience selling tech products, Sculley is lured to Apple by Steve Jobs himself. The Apple co-founder famously pitched the Pepsi exec with the line, “Do you want to spend the rest of your life selling sugared water or do you want a chance to change the world?”

April 6, 1939: John Sculley is born in New York City. He will grow up to be hailed as a business and marketing genius, eventually overseeing Apple’s transformation into the most profitable personal computer company in the world.

After a remarkable stint as president of Pepsi-Cola, Sculley will take over as Apple’s third CEO in 1983. He runs Apple for a 10-year period, guiding the creation of the revolutionary Newton MessagePad.

During Sculley’s decade at the helm, Apple sells more personal computers than any other company. But most people still remember him for his role in kicking Steve Jobs out of Cupertino.

March 25, 1993: Apple executive Gaston Bastiaens bets a journalist that the eagerly anticipated Newton MessagePad will ship before summer ends. The prize? Bastiaens’ well-stocked personal wine cellar, worth thousands of dollars.

The bet takes place at the CeBit trade show in Hanover, Germany. Bastiaens’ outburst comes in response to a reporter’s needling. The gamble not only gives the Newton a release timetable, but also a price target: less than $1,000.

March 17, 1988: Apple sues Microsoft for allegedly stealing 189 different elements of its Macintosh operating system to create Windows 2.0.

The incident, which causes a deep rift between Apple and one of its top developers, paves the way for an epic battle between the two companies that will rage for years.

February 27, 1998: Apple discontinues work on the Newton MessagePad product line, the series of personal digital assistants the company launched five years earlier, and Newton OS, the operating system the devices run upon.

“This decision is consistent with our strategy to focus all our software development resources on extending the Macintosh operating system,” Steve Jobs says in a press release. “To realize our ambitious plans we must focus all of our efforts in one direction.”

January 30, 1995: Apple Computer launches the Newton MessagePad 120, the first truly great device in an unfairly maligned product line.

Coming 18 months after the original Newton MessagePad, the upgraded PDA packs more power — and truly shines once Newton OS 2.0 rolls out.

January 29, 1990: Apple CEO John Sculley appoints Michael H. Spindler as the company’s new chief operating officer.

Nicknamed “The Diesel” on account of his work ethic, Spindler’s new job continues his upward trajectory at Apple. Three years later, he will become CEO.

January 22, 1984: Apple’s stunning “1984” commercial for the Macintosh 128K airs on CBS during the third quarter of Super Bowl XVIII.

Probably the most famous TV ad for a computer in history, the commercial is directed by Alien and Blade Runner helmer Ridley Scott. It very nearly didn’t air, though.

December 4, 1992: Apple engineers demonstrate a “proof of concept” of the Mac operating system running on an Intel computer.

More than a decade before Macs will switch to Intel processors, the astonishing feat is part of an aborted plan to make Apple’s software available on other manufacturers’ hardware. Apple ultimately chickens out, fearing (probably correctly) that such a move would hurt Macintosh sales.

November 21, 1985: Following Steve Jobs’ departure, Apple comes close to signing its own death warrant by licensing the Macintosh’s look and feel to Microsoft.

The deal, between Microsoft co-founder Bill Gates and Apple CEO John Sculley, comes hot on the heels of the Windows operating system’s release. The pact gives Microsoft a “non-exclusive, worldwide, royalty-free, perpetual, nontransferable license to use [parts of the Mac technology] in present and future software programs, and to license them to and through third parties for use in their software programs.”

Oh, boy!

November 8, 1984: After initial Mac sales prove disappointing, Apple CEO John Sculley dreams up the “Test Drive a Macintosh” campaign to encourage people to give the revolutionary new computer a chance.

The promotional strategy advises people in possession of a credit card to drop into their local retailer and “borrow” a Macintosh for 24 hours. The idea is that, by the time potential customers need to return the Mac, they will have built up a bond with it — and realized they can’t live without one of Apple’s computers.

While 200,000 would-be customers take advantage of the offer, Apple dealers absolutely hate it.

October 21, 1991: Apple launches its PowerBook 100 series. The lightweight laptops quickly become one of the most important tech gadgets of all time.

These devices will almost single-handedly turn notebook computers into mainstream technology. Apple’s subsequent success in this category — whether it’s the current MacBooks or even the rise of mobile devices like the iPhone — owes a huge debt to the PowerBook 100 series.

October 19, 1992: Apple launches the Mac IIvx, the first Macintosh computer to ship with a metal case and, more importantly, an internal CD-ROM drive.

The last of the Macintosh II series, the Mac IIvx experiences one of the more notorious price adjustments in Apple history. Within five months of shipping, Apple slashes the computer’s launch price of $2,949 to $1,899. That’s one way to reward early adopters!

October 15, 1993: John Sculley, the former CEO responsible for forcing Steve Jobs out of Apple, is forced to leave the company himself.

When Sculley resigns as Apple’s chairman, he takes $1 million in severance pay, a one-year consulting fee of $750,000, a commitment from Apple to buy his $4 million mansion and $2 million Lear jet, and $2.4 million in stock options. Total take: around $10 million.

September 16, 1985 and 1997: Twice on this day, Steve Jobs makes significant moves with regard to his career at Apple. In 1985, he quits the company he co-founded. Then, a little more than a decade later, he officially rejoins Apple as its new interim CEO.

In terms of the emotions associated with those historic occasions, it’s hard to think of two more polarizing days in Jobs’ life.

August 14, 1991: As Apple and Microsoft head to court to battle each other, the tide begins to turn against Cupertino and its claims that Windows unlawfully copies the look and feel of Mac OS.

The case concerns whether key elements of Apple’s operating system are original enough for copyright protection. The decision turns out to be a major blow against Apple — and the start of the company’s 1990s decline.

August 2, 1993: Apple debuts the MessagePad, the first product in its Newton line of handheld personal digital assistants.

The most unfairly maligned product in Apple history, the Newton is a revolutionary device. It predates Apple’s push toward app-based mobile devices 14 years later. Often dismissed as a failure, the Newton ranks near the top of the list of Apple’s most influential creations.

July 25, 1989: Apple suffers a major setback in its copyright-infringement lawsuit against Microsoft for allegedly stealing the Mac’s “look and feel” to create Windows.

Apple sued Microsoft on 189 counts of copyright infringement relating to Windows 2.0.3. The judge overseeing the case throws out 179 of them. This paves the way for Microsoft’s dominance over Apple in the coming decade.

June 25, 1985: Microsoft co-founder Bill Gates sends a memo to Apple execs suggesting that Cupertino should license its Mac operating system and additional technology to other companies.

Apple CEO John Sculley and Macintosh boss Jean Louis Gassée ignore the advice of the 30-year-old Gates, who at the time is best known as a Mac developer. Five months later, Microsoft releases Windows 1.0.

June 20, 1994: Apple launches eWorld, a subscription service for Mac owners that’s designed to compete with America Online and other nascent online properties.

Part messaging service and part news aggregator, Apple envisions eWorld competing with heavy hitters like AOL, Delphi, CompuServe and Prodigy. Unfortunately, Apple’s online service is doomed from the start.

June 18, 1993: John Sculley steps down as Apple CEO after a 10-year run.

Sculley is asked to leave by the Apple board after AAPL shares collapse from a high of $4.33 in 1992 to 73 cents the following year. He hands over the CEO role to Michael Spindler before briefly taking the role of Apple chairman, prior to departing altogether.

May 29, 1992: Apple demonstrates the Newton MessagePad for the first time, showing how the upcoming PDA can be used to order a pizza and pull off other time-saving tricks.

Hailed by Apple CEO John Sculley as “nothing less than a revolution,” the Newton is Apple’s first major new product since the Macintosh eight years earlier. During the Newton demo at the Consumer Electronics Show in Chicago, Apple shows how people can customize a pizza by moving topping icons on a symbolic pie, then fax the order straight from the device.

May 27, 1986: An exiled Steve Jobs takes a shot at Apple after the company ditches Chiat/Day, the ad agency that created the iconic “1984” Macintosh ad.

In a full-page ad published in The Wall Street Journal, Jobs says the move to competing ad agency BBDO shows that “caretakers” rather than “builders” now run Apple. From his perspective, it confirms that Apple has lost its revolutionary spirit.

May 26, 2010: In a massive milestone, Apple passes Microsoft to become the world’s most valuable technology company.

The changing of the guard proves particularly amazing given that, just 15 years earlier, Apple looked close to dead, while Microsoft dominated the tech world thanks to Windows.
