While tablets may be getting the bulk of the attention in the media, a new study from the Pew Internet Project found e-readers are actually growing at a faster rate in the United States.
In a survey of more than 2,000 American adults, the market research firm found e-reader ownership doubled between November 2010 and May 2011, increasing from 6 percent of adults to 12 percent.
Tablets, in contrast, have not enjoyed the same pace, increasing from 5 percent ownership to 8 percent during the same period.
However, as more tablets are introduced to the market, this trend may change. As of now, Apple's iPad dominates the tablet market. But more devices are arriving every month, including tablets from HP, Research In Motion and a handful of devices based on Google's Android mobile operating system.
Earlier this year, research firm IDC released a report that stated the United States represents nearly three-quarters of the global e-reader market. According to the report, 14.7 million e-readers are expected to ship this year in the United States, with Amazon's Kindle leading the way.
