Apple’s iPhone business now represents a whopping 40% of the company’s revenue, according to
Business Insider’s “chart of the
day.� Remarkably, that’s a share of the business that didn’t exist three years ago. Now, for three quarters and counting, the iPhone is
Apple’s biggest revenue generator. During the March quarter, iPhone revenue grew 124% year-over-year to $5.4 billion -- or 40% of Apple’s $13.5 billion in total
revenue. “Because of high profit margins on the iPhone, it’s likely Apple’s biggest profit contributor, too,� suggests
Business Insider. “But that’s another chart. Apple’s second-biggest business is its Mac computer division, which grew 27% year-over-year in the
March quarter to $3.8 billion -- or 28% of Apple’s overall sales. How the iPad will impact Apple’s revenue picture remains to be seen, though early reports
suggest that the tablet device could eventually give the iPhone a run for its money.
