The verdict is in for third-quarter tablet shipment numbers: Shipments are increasing and the brand gap is shrinking. According to IDC Worldwide Tablet Tracker, 47.6 million tablets were shipped in the third quarter, a 36.7 percent year-over-year growth.

Over 35 percent of total tablet sales fall into the "other" brand category. Following is a breakdown of the top-five tablet brands according to IDC.
