Amazon Lights the Android World on Fire
In just two years, tablet computing has gained unprecedented traction. According to research firm Strategy Analytics, global tablet shipment more than doubled during the last three months of 2011, rising to 26.8 units, up from 10.7 million a year earlier. And while Apple continues to dominate the tablet category, having sold a record 15.4 million units during the final quarter of 2011, Android OS tablets have increased their share of the tablet category, growing from 29% in Q4 2010 to 39% in Q4 2011.
The increase in market share is due largely to the entry of the Kindle Fire by Amazon. With Flurry in tens of thousands of Android apps, including many of the most popular, the company estimates that it tracks over 20% of all consumer sessions on more than 90% of all Android devices each day. A session is defined as the launch and subsequent exit (or pause for more than 10 seconds) of an app. For example, a consumer may play a game in one sitting for five minutes. Let’s take a look at the data.
