Whether you love him or hate him, Dave Portnoy is a household name for sports fans. Portnoy rose to fame after founding Barstool Sports in 2003. While the brand struggled during its early days of just being a newspaper, Portnoy has since turned it into a major media company with a huge social media presence. (Barstool Beach House, anyone?) Over the years, Portnoy has become known for his controversial presence online but has also gained a massive following for his One Bite pizza reviews. Whatever corner of the internet you're on, there's no doubt that you've heard of Portnoy.
