The bad news for Apple is that revenue from its two biggest segments -- Europe and the Americas -- have begun to contract, not just as a percentage of total revenue, but in dollar terms as well. The good news is that Japan, Asia Pacific and Greater China have so far more than taken up the slack. In Q1 2014, Apple's combined Asian sales were $17.4 billion, more than Europe ($13 billion) and closing in on the Americas ($20 billion).
Fortune offers a chart to illustrate that share of total revenue from Q1 2010 to Q1 2014 has increased 62% for China/Asia Pacific and 49% for Japan. During the same time it decreased 16% for Retail, 22% for the Americas, and 39% for Europe.
