1. The book market is changing (more "creative destruction"), as ebook sales are growing exponentially and traditional book sales are in decline:
"The Association of American Publishers recently released figures for the past year ending in January 2011, and the results are startling: eBooks have taken off in a large way, with sales of eBooks from various book stores doubling year-over-year from January 2010; close to 115%. The report also cast gloom over sales of traditional paper books, which declined approximately 30% over the same period. Hardcover sales were the biggest loss, dropping over 11% from January 2010 to January 2011."
