Apple is bracing for its first sales decline in 13 years, despite selling a record 74.8 million iPhones in the final three months of 2015, in what may prove to be a turning point for the world's most valuable company, according to AP. The tech giant says revenue could fall at least 8.6 percent during the January-March quarter, compared with a year earlier. Analysts say the latest iPhone models aren't providing the boost Apple needs to match the massive sales growth it enjoyed last year. Apple executives painted the downturn as a momentary hiccup. But they also acknowledged the company is working to broaden its business beyond the iPhone itself, which in recent years has provided the bulk of Apple's revenue.
