This IDC update analyzes the performance of the PC market in 4Q15. Worldwide PC shipments fell 11.3% year over year (YoY) in 4Q15 to 71.3 million units, marking it the end of an extremely poor year for the PC market. The shipment total represented the worst fourth quarter result since 2006. In total, 275.8 million PCs were shipped in 2015, the lowest total since 2008. The worldwide PC market contracted by 10.6% in unit volume, the worst yearly market contraction ever recorded. For much of 2015, the PC market suffered from poor macroeconomics. Global economic concerns, currency weakness in most regions, and political instability in some areas muted PC demand and exacerbated inventory issues in most channels in most regions.

Worldwide and U.S. PC Market Shares, 2015 (forthcoming), a subsequent market share document, will cover 2015 in totality with more detail. Highlights of this document include:
