Cult brands do not confine to products or services provided by businesses. Cult brands may include influential people, for instance, celebrities. The Oprah Winfrey Show rapidly flourished into a cult brand in 1986. Oprah's topic of discussion and debate were of great interest to her audience, while her advice and recommendations were found highly influential. For example, Oprah's book recommendations helped many novels become best sellers. Furthermore, her endorsement of the current president of the United States, Barack Obama's presidential election in 2008 proved efficacious.
