From The Bookseller:
US publishers’ sales of e-books more than doubled in 2011, meaning that the digital book is now the dominant single format within the trade sector’s adult fiction category, representing 30% of all adult fiction book sales. But there was also strong growth in the children’s sector, and through selling direct, as US trade publishers grew sales by 0.5%.
According to BookStats, which examines US publishers’ annual net sales revenues and net units (including adult, non-fiction, children’s books and religious publishing), e-book sales rose from $869m, or 6% of trade, in 2010 to $2.1bn, or 15% of net revenues, in 2011. E-book units also more than doubled, from 125m e-books to 388m.
However, in the adult fiction sector, e-books became the dominant single format with 30% of total net publisher dollar sales.

The combined print formats still represented the majority of publishers’ revenue in the adult fiction category, at $2.8bn.
