No. 1 Apple
With the release of the first iPad, Apple became the inventor of the tablet. At the conclusion of third quarter, Apple remains at the top of the tablet game, holding 29.6 percent of the total market share, a drop from 40.2 percent during the same quarter of the previous year. The company shipped 14 million devices during the third quarter of 2012 and increased to only 14.1 million devices during the third quarter of 2013. Apple's brand new iPad Mini with retina and the iPad Air were both unveiled after the start of the fourth quarter -- just in time for the holidays. In its report, IDC said it "expects Apple to enjoy robust shipment growth during the fourth quarter."
