Bull is an American drama series created by Michael S. Chernuchin that aired on TNT from August 15, 2000 to January 31, 2001. The show's name is in reference to the bull market, but the airing of the series coincided with the dot-com bubble crash that turned what had until then been a bull economy in the United States into a bear market. On February 2001 the series was cancelled after airing 12 of the planned 20 episodes.
