That is remarkable, considering that the Kindle has only been around for four years.

E-book sales are up 146 percent over last year, while hardback sales increased 6 percent and paperbacks decreased 8 percent.

Rupert Murdoch once described them as the "rivers of gold"--the lucrative classified-advertising revenues that flowed into big newspaper groups. But the golden rivers are being diverted online as the Internet breaks the grip that local and regional newspapers once held over their advertising markets.
