More confirmation of the seismic changes in publishing, this time from Barnes & Noble VP Marc Parrish at the recent GigaOm Big Data conference in New York:

"The book business is changing more radically now, and quicker, than movies or music or newspapers have, because we're doing it in a matter of months…In [the] next 24 months is when this business will totally shift."

B&N predicts that, for 2011, the company will sell 18 million ereaders. That's compared with the 900,000 they sold in 2009.
