E-books are rewriting bookselling

By Jeffrey A. Trachtenberg in The Wall Street Journal :

...the digital revolution sweeping the media world is rewriting the rules of the book industry, upending the established players which have dominated for decades. Electronic books are still in their infancy, comprising an estimated 3% to 5% of the market today. But they are fast accelerating the decline of physical books, forcing retailers, publishers, authors and agents to reinvent their business models or be painfully crippled.

"By the end of 2012, digital books will be 20% to 25% of unit sales, and that's on the conservative side," predicts Mike Shatzkin, chief executive of the Idea Logical Co., publishing consultants. "Add in another 25% of units sold online, and roughly half of all unit sales will be on the Internet."
