Random House saw eBook sales triple in the first half of 2011, as compared to sales in the same period in 2010.

Bertelsmann, the group that owns the publisher, released its revenues for the first half of 2011 earlier this week. Random House revenues hit €787 million, down slightly from the company’s revenues in 2010 for the same period which hit €791 million. However, the earnings before interest and taxes (EBIT) was €69 million, up from €40 million. The publisher attributed this favorable EBIT to strong U.S. performance.

According to Random House, overall gains were driven by bestsellers, and eBook sales across all territories. In the U.S., digital sales accounted for more than 20 percent of all revenues. At the reporting date, Random House imprints had more than 27,000 eBooks available worldwide.
