Brigham Young University economics professor Richard Butler, whose findings were published in the latest issue of the journal Publishing Research Quarterly, says Oprah Winfrey's book recommendations sold more books than anything previously seen in literature.
"Using USA Today's weekly 150-item best-seller list, Butler and his team of students went about examining the 45 non-children's titles Winfrey picked from her book club's inception in 1996 until she announced its end in 2002.
"Of those books, only 11 had been on the best-seller list before her recommendation, and none of them had gone beyond No. 25. Of the first 11 books that Winfrey picked, all went to at least No. 4 within a week, Butler said." (New York Times)
