USA Today says: "O no!"
Last week's news that Oprah is closing shop on September 9, 2011 has the publishing world wondering: What now? All 63 Oprah book club picks since 1996 have made USA Today's Top 50 list of bestsellers and 19 hit No. 1. Eckhart Tolle's A New Earth was No. 1 longest at 11 consecutive weeks.
Oprah's influence goes beyond book club picks: recent appearances on Oprah by Mackenzie Phillips and Sarah Palin helped make them best sellers.
