Bull is an American drama series created by Michael S. Chernuchin. It was TNT's first original series, and was cancelled in the middle of Season 1. 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. Bull is about a group of Wall Street investment bankers that risk everything to break away from an established firm and start their own company. Leading the way is Robert "Ditto" Roberts III, the brilliant grandson of the founder of their former company who must betray his family heritage in order to stake a claim to his own life. His partners - Corey Granville, Marty Decker, Carson Boyd, Alison Jeffers and Marissa Rufo - each with a separate agenda, risk losing everything to join him in the new rival start-up firm that will answer the call of the new economy.
