2007: Kindle Released
2010: Kindle eBook sales
outpace hardcover sales
2011:
"I predict we will surpass paperback sales sometime in the next nine to 12 months"
2012-2013?:
"Sometime after that, we'll surpass the combination of paperback and hardcover"
I'm going with Bezos on this one-Amazon will be selling more eBooks than paper books by 2012-2013, with the rest of the industry following close behind.
