It shouldn’t surprise anyone that Apple (NASDAQ: AAPL) makes most of its money from the iPhone. After its initial launch in mid-2007, the iPhone gradually replaced the iPod as Apple’s biggest revenue driver. Between fiscal 2008 and 2016, Apple’s iPhone shipments surged from 11.6 million to 211.9 million. During that period, Apple’s annual revenue rose from $32.5 billion to $215.6 billion.
