FORTUNE — IDC’s report on the worldwide tablet market for the third quarter of calendar 2012 — before Apple (AAPL) released the new iPad mini and iPad 4 — show the growth of the global market slowing and Apple’s share of that market falling from to 50.4% from 65.5% in calendar Q2.
Although neither Samsung nor Amazon (AMZN) release tablet sales or shipment figures, IDC estimates that the two companies’ shipments “surged” last quarter. “Most notable,” according to its press release, “was the impressive quarter turned out by Samsung—driven by its Galaxy Tab and Note 10.1. Samsung shipped 5.1 million tablets worldwide in 3Q12, up 115.0% from 2Q12; that’s an increase of 325.0% from 3Q11, when it shipped 1.2 million tablets.”
