After suffering a decline in revenue last year for the first time since introducing the iPhone, Apple Inc. returned to growth in the 2017 fiscal year, and showed signs of turning around in several important areas in Thursday’s fourth-quarter report. Apple AAPL, +3.37% sales are driven by the iPhone, which accounts for more than half of all revenue the tech giant collects, so investors were rightly focused on smartphone sales in its blowout earnings report Thursday afternoon. However, Apple’s other businesses are larger than many whole companies, and three segments that had been struggling showed signs that they could return to growth and help support iPhone sales. China sales: Sales in greater China showed year-over-year growth in the fiscal fourth quarter for the first time since the holiday-shopping quarter of 2015. Sales jumped 12% from the year-ago period to $9.8 billion, easily surpassing estimates of less than $9 billion.via
