This morning, Apple announced that it had sold 3 million iPads over three days. The iPad Mini and iPad 4 release last week met smaller crowds than expected, but still doubled the iPad 3’s 1.5 million opening weekend sales. Of course, this report is also for two devices, not one -- the new iPad 4 and the iPad Mini. 

With Apple going strong, the International Data Corporation has preliminary data indicating that Android tablets are closing the gap in the tablet marketplace. As we reported last week, the Android operating system is now estimated run on 75% of smartphones, but it appears Apple is still the dominant tablet manufacturer.

In a report released today by IDC, data shows that the overall tablet market has grown 49.5% over the past year. While Apple sales were strong with 26.1% market growth, Android sales skyrocketed with Samsung shipping 5.1 million tablets worldwide in the third quarter of 2012, up 115% from the second quarter of 2012. Overall, Samsung saw an increase of 325% from 3Q11.

Android’s big tablet push sent Apple’s market share down 9% from 59.7% in 2011 to 50.4% in 2012. At this rate, it might not be long before Android emerges as the tablet leader.
