OMAHA — Mutual of Omaha is suing Oprah Winfrey over rights to the phrase "aha moment."
The insurer said it began using the slogan "official sponsor of the aha moment" in its advertising in February. But in a letter Tuesday to Mutual of Omaha, Marc Rachman, an attorney for Winfrey's production company, Harpo Productions Inc., demanded the insurer stop using the phrase.
