Large publisher Simon and Schuster reported a surprising increase in their first quarter earnings:

Digital publishing revenue went from $3.6 million to $12 million in Q1, a 233 percent increase. According to a paidContent story, this means " digital now makes up 7.9 percent of S&S revenue."

The surprising thing about that increase is that it's only 7.9 percent of their revenue; books really are the final frontier when it comes to digital conversion. On the whole, though, Simon and Schuster's sales fell 6% in the first quarter.
