In late 2015, HP was reborn as a PC maker following a split of its parent organization, Hewlett-Packard. At the time, HP was a lost cause, and its double-digit decline in PC shipments was a main reason for the split.
The new HP then set out to reclaim its spot as the world's top PC maker from Lenovo, a title it lost in 2013. It reached the goal in the first quarter of 2017, during which its PC shipments grew by 13.1 percent year over year.
A series of cool products and decisions to cut off low-margin products helped HP return to the top. Lenovo's struggles also played a part, but HP's strong performance in North America was a deciding factor, IDC said.
