Madison Square Garden Entertainment Corp. is an American entertainment holding company based in New York City. The company was established in 2020 when The Madison Square Garden Company spun off its non-sports assets as an independent, publicly traded company. MSG Entertainment controls live events at Madison Square Garden, both in the arena and in 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 controls the operations of the Chicago Theatre, co-booking at the Wang Theatre in Boston, and an entertainment venue in Las Vegas known as Sphere. MSG Entertainment also produces the Radio City Christmas Spectacular at Radio City Music Hall and formerly in other venues around the United States. On March 26, 2021, MSG Entertainment announced that it would acquire the regional sports network group MSG Networks in an all-stock deal, reuniting it with its namesake venue; MSG Networks had originally been spun out from The Madison Square Garden Company in 2015. The acquisition was completed in July 2021. Wikipedia
