The iPad was released a little over two years ago, and all it’s done for Apple since then is make them a lot of money. 25% of smartphone users now own or regularly use a tablet of some sort, suggesting that “smartphone ownership is highly predictive of tablet adoption in the current market,” according to ComScore, the company that conducted the survey.

Tablet ownership has grown from 9.7% to 23.6% just in the past six months. “Tablets are one of the most rapidly adopted consumer technologies in history and are poised to fundamentally disrupt the way people engage with the digital world both on-the-go and perhaps most notably, in the home,” says the ComScore blog. “It’s not surprising to see that once consumers get their hands on their first tablet, they are using them for any number of media habits including TV viewing.”

One of the biggest factors contributing to the high usage of iPads is their reasonably-sized screens. Many of the screens are almost as big as a small LCD computer screen. People with tablets, says ComScore, are three times more likely to watch videos on their devices than smartphone owners. This also may be why smartphone owners are more likely to own tablets – tablets are essentially smartphone technology with bigger, more accessible screens.

The majority of tablet users range in age from 25-54 and are usually wealthier. The more wealthy you are, the more likely you are to own a tablet of some sort. Unsurprisingly, the Apple iPad is by far the most popular tablet, stealing nearly 50% of the market.
