September 22, 2014: Apple notches a new sales record with iPhone 6 and iPhone 6 Plus, selling an astonishing 10 million units in the first weekend the handsets go on sale.

The eagerly anticipated smartphones bring a redesigned form factor that will persist for years. The most obvious change? Larger 4.7-inch and 5.5-inch displays built to lure phablet fans. The iPhone 6 and 6 Plus also boast an A8 chip, improved iSight and FaceTime cameras, and — significantly — Apple Pay.

“Sales for iPhone 6 and iPhone 6 Plus exceeded our expectations for the launch weekend, and we couldn’t be happier,” Apple CEO Tim Cook says in a press release. “We would like to thank all of our customers for making this our best launch ever, shattering all previous sell-through records by a large margin.”

September 19, 2014: The iPhone undergoes its biggest upgrade — both figuratively and literally — since the original, with the launch of the iPhone 6 and iPhone 6 Plus handsets.

The iPhone 6 brings a new 4.7-inch form factor, while the iPhone 6 Plus boasts a massive 5.5-inch design. The previous-generation iPhone 5 measured only slightly taller than its 3.5-inch predecessors. But with the iPhone 6, Apple abandons that strategy for the first time to take on big-screen Android “phablets.”

September 18, 2013: iOS 7 launches with a radical redesign that divides the tech world.

The biggest overhaul Apple’s mobile operating system has seen in years, iOS 7 ditches the skeuomorphic objects, dials and textures of previous iterations. Instead, it boasts stark patches of white space, simpler icons and more abstract controls for settings. The Jony Ive era of software design is truly underway.

September 17, 2012: On the back of record iPhone 5 preorders of 2 million in 24 hours, Apple’s stock price hits a new all-time high. For the first time in history, AAPL breaks the $700 mark in after-hours trading. Passing the milestone cements Cupertino’s place as the world’s most valuable publicly traded company.

Amazingly, the new record is $270 a share higher than at the start of the year. Apple stock rose 65% in just nine months.

September 15, 2014: Responding to its disastrous U2 album giveaway, Apple provides iPhone owners with a tool for wiping all signs of Songs of Innocence from their phones.

It comes after one of the strangest PR debacles in Apple history. After putting a free copy of U2’s latest release on every iPhone owner’s handset as a special promotion, millions find themselves with an album they didn’t order in their iTunes library. Many weren’t happy about it.

September 14, 2010: Security workers reportedly stop Steve Jobs at Japan’s Kansai International Airport. The reason? The Apple CEO supposedly tried to bring ninja throwing stars onto his private plane while heading home from vacation.

It’s one of the most bizarre Jobs stories ever. Apple, however, quickly spoils the internet’s fun. Cupertino issues a statement describing the reports as “pure fiction” (although Apple acknowledges that Jobs visited Japan over the summer).

September 12, 2012: The Lightning connector replaces Apple’s aging 30-pin interface, a proprietary data and power connector that debuted on the iPod Classic in 2003. The slender and capable new Lightning port debuts in the iPhone 5, bringing big improvements — and no small amount of controversy.

Apple soon will build the Lightning connector into many other products, including iPad, iPod and accessories. It’s used to charge the mobile devices as well as transfer data to a Mac or PC.

September 1, 2010: Apple’s new music-focused social network, Ping, ships as part of iTunes 10. Apple says the service will let users discover new music and more easily follow their favorite artists.

Ping racks up 1 million signups in the first 48 hours. Nevertheless, Apple’s social network is doomed from the start.

August 24, 2011: With his health worsening, a cancer-stricken Steve Jobs steps down from his role leading Apple. Tim Cook assumes the role of Apple’s seventh CEO.

“I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple’s CEO, I would be the first to let you know,” Jobs writes in his retirement letter to the Apple board. “Unfortunately that day has come.”

August 23, 2011: United Airlines says it will hand out 11,000 iPads to its pilots. It’s the largest rollout yet of Apple tablets as a replacement for the weighty flight bags previously carried by aircrews.

Going paperless saves around 16 million sheets of paper each year, the equivalent of 1,900 trees not cut down. Even better, the weight difference between the 1.5-pound iPad and the 40-pound flight bag saves 326,000 gallons of jet fuel per year!
