In a declining tablet market, Amazon's is gaining market share with its set of Fire devices.
According to IDC, Amazon grew its market share 38.7 percent in the third quarter. Amazon ended the third quarter with 10.9 percent share, up from 7.5 percent a year ago. Amazon also shipped 4.4 million units in the third quarter, up from 3.1 million a year ago.
There were 40 million tablets shipped in the third quarter, down 5.4 percent from a year ago, said IDC.
IDC's standings highlight Amazon's aggressive hardware strategy. In addition to a barrage of Echo devices, Amazon has continued to release a series of tablet upgrades. In addition, Amazon pitched its 7-inch tablet for less than $30 during Prime Day.
Amazon's hardware strategy is likely a loss leader, but the devices build long-term relationships with customers, fuel content sales and drive Prime subscriptions and e-commerce. Amazon's tablets have also become another vehicle for Alexa. See:

On Apple's September quarter earnings conference call, CEO Tim Cook touted iPad's double digit growth for the second quarter in a row. Apple said iPad sales were up 11 percent in its fiscal fourth quarter.
Customers have responded very positively to the new iPad lineup. And with the launch of iOS 11, the iPad experience has become more powerful than ever with great new features for getting things done, like the new dock, files app, drag-and-drop, multitasking and more power than most PC notebooks.
