To say that Apple dominates the tablet market would be an understatement. The iPad has been successful enough to not only run other companies out of the tablet-making business, but it has also been enough to make even PC manufacturers nervous.

We’ve seen statistics before regarding Apple’s share of the tablet market, but we had no idea the numbers were this bleak for the competition. According to a recent NPD Group report, there has only been 1.2 million non-iPad tablets sold in the United States this year…

That’s staggering when you consider that Apple sold over 11 million iPads last quarter. Sure, that number comes from total global sales, but it also comes from just a three month period. The aforementioned number of US-based tablet sales was over a 10 month span. Ouch.

NPD’s research also revealed some other interesting facts. Apparently, HP sold the most non-iPad tablets in the US this year. That probably has something to do with the $99 fire sale it hosted a few months ago that reportedly cost the company over a billion dollars.

Right behind HP was Samsung, who has been in the tablet game longer than everyone but Apple. In fact, the Galaxy Tab is the reason behind several Apple-lead lawsuits against the Korean company.

The tablet market landscape is quickly changing. Companies like Barnes and Noble and Amazon have recently released low-cost, capable slates that could draw in a lot of consumers during this economic slump. It’ll be interesting to see what these numbers look like a year from now.
