Global PC market shrinks 11.8% year-over-year:

With shipments totaling nearly 16.4 million PCs in 2Q15, the U.S. market shrank -3.3% from the same quarter a year ago. Although most vendors saw volume decline, gains from Apple and Lenovo helped limit the overall decline.

As someone who has been following the company since the mid-90s, it's amazing that Apple has gotten big enough that their sales are impacting the overall market in a meaningful way.
