Lee Fenton, the new chief executive officer of Bally’s Corp., wants to create similar programming as he looks to promote the company’s sports-betting business in the U.S. The British executive took the top job there following its $2.7 billion merger with his U.K.-based Gamesys Group Plc. The deal, which closed this week, unites a large European online betting house with Bally’s, which owns 14 casinos in 10 states.
