In 1990, Bannon and several colleagues from Goldman Sachs launched their own company Bannon & Co., a boutique investment bank specializing in media. In one of Bannon & Co.'s transactions, the firm represented Westinghouse Electric which wanted to sell Castle Rock Entertainment.[56] Bannon negotiated a sale of Castle Rock to Turner Broadcasting System, which was owned by Ted Turner at the time.[66] Instead of a full adviser's fee, Bannon & Co. accepted a financial stake in five television shows, including Seinfeld, which was in its third season. Bannon still receives cash residuals each time Seinfeld is aired.[66] Société Générale purchased Bannon & Co. in 1998.[56]
