From Digital Book World:
Revenues at Random House grew to €947 million ($1.19 billion) in the first half of 2012, up from €787 million in the first half of 2011 on the strength of selling 30 million copies of Fifty Shades of Grey, half of which were e-books.
. . . .
“Growth in our e-book sales, which continued to rise significantly in each of our divisions, was complemented by our increasing market share among physical retailers,” said Random House chairman and CEO Markus Dohle in a letter to the company.
According to a company spokesperson, digital revenues as a share of total company revenues rose in the first half of 2012 to 27% in the U.S., up from 20% in the first half of 2011. Perhaps more significant for the world’s largest publisher is that worldwide digital revenues were 22% of total revenues.
