Back in January this year, Apple recorded a blockbuster of a quarter thanks to holiday sales of its new, larger-screened handsets. It sold a whopping 74.5 million iPhones in the last three months of 2014, chalking up $74.6 billion in revenue in the process. While today's second quarter results don't quite match that number, Cook & co. still managed to rake in a respectable amount of cash: According to the report, Apple made around $58 billion and sold close to 61 million iPhones in the first three months of 2015 alone. That makes this the most successful March quarter in the company's history. This is in large part due to Apple's rising popularity in China, having brought in $16.8 billion in revenue from the country in the past three months. Indeed, China is now Apple's second-biggest market (Americas is still the first), with Europe falling to third place.
