David Portnoy, the outspoken founder of Barstool Sports, is once again the owner of his media brand, after buying it back from Penn Entertainment . Barstool Sports was valued at $606 million in February, when Penn bought the rest of the company it didn't already own. Portnoy, who founded Barstool Sports in 2003, said in a post on Tuesday that Penn and Barstool had "gone our separate ways." Penn sold Barstool at the same time that it announced an online sports-betting deal with Disney -owned ESPN. Penn will have the right to 50% of the gross proceeds in the event that Portnoy sells or monetizes Barstool, the release said.
