Often a presenter's biography will mention a book he or she has authored, and sometimes the speaker is even an author by trade. In fact, currently among the top 20 TED Talks (determined by views) are Bonk and Gulp author Mary Roach (No. 19) and Eat, Pray, Love author Elizabeth Gilbert (No. 13).
Some other author TED vets you may recognize include Harry Potter creator J.K. Rowling, McSweeney's founder and editor Dave Eggers, food and agriculture expert Michael Pollan, The Joy Luck Club author Amy Tan, and The Fault in Our Stars author John Green.
But there was a moment, a week or so ago, when something truly new happened: our two bestselling books were Lean In by Sheryl Sandberg and Daring Greatly by Brene Brown. Each was the debut book by a TEDTalker-turned-author who used her presentation as the basis of her book. Is it a new trend? Is there such a thing as a "TED effect" now?
It's too soon to tell, but we're keeping our eyes open. Meanwhile, TED has teamed up with Kindle Singles to publish shorter nonfiction (around 20,000 words) pieces by many TED Talks participants. You can find them here.
