The Discover Card is a credit card, issued primarily in the United States. It was announced by Sears in 1985 and was introduced nationwide the following year. Discover was part of Dean Witter, and then Morgan Stanley, until 2007, when Discover Financial Services became an independent company. Novus was once the major processing center that partnered with the company. The Novus logo was retired, replaced by the Discover Network logo. Discover Card is the third-largest credit card brand in the United States, with nearly 61 million cardholders.
