Following the release of findings from the Bowker Market Research's Global eBook Monitor on March 27, the Pew Research Center in the United States, a non-partisan "fact tank" that provides information on the issues, attitudes and trends shaping America and the world, also released results of various recent surveys on e-reading in that country.

According to a survey conducted in February 2012, 21 percent of American adults said they had read an ebook in the past twelve months. The average reader of ebooks said he or she had read 24 books in that period of time, compared with an average of 15 books by a non-ebook consumer.

Another survey conducted in December 2011 shows that printed books still dominate the world of book readers. While 17 percent of American adults said they had read an ebook in the previous year, 72 percent said they had read a printed book. The remaining 11 percent listened to an audiobook in that period of time.

Perhaps the most interesting result of the Pew research Center's surveys derives from its broad definition of e-content. According to a survey ending in December 2011, for example, some 43 percent of respondents aged 16 and above said they had either read an ebook in the past year or had read other long-form content such as magazines, journals and news articles in digital format on an ebook reader, tablet computer, desktop computer or mobile phone.
