Oprah's Book Club launches (1996)( George Burns / Harpo Productions )
Oprah launched Oprah's Book Club, a discussion segment from "The Oprah Winfrey Show," on Sept. 17, 1996. Her first pick was "The Deep End of the Ocean" by Jacquelyn Mitchard. Since then, she's chosen 65 selections for her book club, offering members Q-and-As with authors, character guides, reading questions, quizzes and video.
The club's popularity spawned the "Oprah effect" -- when lesser-known books launch onto bestseller lists because of Winfrey.
