"The Oprah Effect"

The power of Winfrey's opinions and endorsement to influence public opinion, especially consumer purchasing choices, has been dubbed "the Oprah Effect ". The effect has been documented or alleged in domains as diverse as book sales, beef markets, and election voting. Late in 1996, Winfrey introduced the Oprah's Book Club segment to her television show. The segment focused on new books and classics and often brought obscure novels to popular attention. The book club became such a powerful force that whenever Winfrey introduced a new book as her book-club selection, it instantly became a best-seller; for example, when she selected the classic John Steinbeck novel East of Eden, it soared to the top of the book charts. Being recognized by Winfrey often means a million additional book sales for an author. In Reading with Oprah: The Book Club that Changed America (2005), Kathleen Rooney describes Winfrey as "a serious American intellectual who pioneered the use of electronic media, specifically television and the Internet, to take reading – a decidedly non-technological and highly individual act – and highlight its social elements and uses in such a way to motivate millions of erstwhile non-readers to pick up books."

When author Jonathan Franzen 's book was selected for the Book Club, he reportedly "cringed" and said selected books tend to be "schmaltzy". After James Frey 's A Million Little Pieces was found to contain fabrications in 2006, Winfrey confronted him on her show over the breach of trust. In 2009, Winfrey apologized to Frey for the public confrontation. During a show about mad cow disease with Howard Lyman (aired on April 16, 1996), Winfrey said she was stopped cold from eating another burger. Texas cattlemen sued her and Lyman in early 1998 for "false defamation of perishable food" and "business disparagement," claiming that Winfrey's remarks sent cattle prices tumbling, costing beef producers $11 million. Winfrey was represented by attorney Chip Babcock and, on February 26, after a two-month trial in an Amarillo, Texas, court, a jury found Winfrey and Lyman were not liable for damages. During the lawsuit, Winfrey hired Phil McGraw 's company Courtroom Sciences, Inc. to help her analyze and read the jury. Winfrey's ability to launch other successful talk shows such as Dr. Phil, The Dr. Oz Show, and Rachael Ray has also been cited as examples of "The Oprah Effect".
