The iPhone was announced on January 9, 2007 and released for sale on June 29. Here’s Steve Ballmer, a few days after Steve Jobs unveiled Apple’s new smartphone at Macworld:
Five years later, the iPhone, by itself, is a bigger business than Microsoft. As in the entire Microsoft corporation.
It looks like Apple’s business is mainly about iPhone. And while it’s true that the iPhone is responsible for over half of Apple’s total revenue, it’s important to consider that Apple’s total pie is now significantly larger than Microsoft’s. Actually, it’s more than twice as large.
Put another way: Apple’s iPhone business alone is larger than all of Microsoft’s businesses combined.
And — just as remarkably — if you took away Apple’s iPhone business from the chart, the remaining Apple businesses would still be larger than Microsoft’s total business. And Apple’s earnings would look a lot more evenly distributed then.
