I. Non-fiction rules!
Starting as far back as 50 years ago, non-fiction set out to crush fiction in the book world. In the 1920s, fiction outsold non-fiction four to one; by the 1960s, non-fiction had flipped the script, outselling fiction four-to-one. Fast forward to the 21st century, when the sale of memoirs increased 400% between 2004 and 2008, and non-fiction still clobbers fiction on the commercial front. Where once the novel was king, books of truth now strode the land like giants. What happened?
