Madison Square Garden Entertainment Corp. is an American entertainment holding company based in New York City, controlled by the family of Charles Dolan. The first incarnation of the company was established in April 2020 when The Madison Square Garden Company spun off its non-sports assets as an independent, publicly traded company. In April 2023, Madison Square Garden Entertainment was renamed Sphere Entertainment, and spun off its theatres and event businesses as a new company that inherited the Madison Square Garden Entertainment name. Sphere Entertainment holds a minority stake in the spin-off. MSG Entertainment owns and operates its namesake Madison Square Garden in New York City, including the arena and The Theater at Madison Square Garden. In addition to the Garden itself, MSG Entertainment operates two other theaters in Manhattan: Radio City Music Hall and the Beacon Theatre. Outside New York City, MSG Entertainment owns and operates the Chicago Theatre. MSG Entertainment also produces the Radio City Christmas Spectacular at Radio City Music Hall and formerly in other venues around the United States. Wikipedia
