Themeparks LLC was formed by Ed Hart and is based in Louisvilled, Kentucky. Themeparks' first park was Kentucky Kingdom which it bought in 1990. In 2008 Themeparks sold Magic Springs Theme Park in Hot Springs, Arkansas to PARC Management, LLC and attempted to buy back Kentucky Kingdom.
In 1997, Kentucky Kingdom was sold to Premier Parks, which in 1998 purchased Six Flags Theme Parks from Time Warner. In 1998 Kentucky Kingdom became Six Flags Kentucky Kingdom. Currently Themeparks LLC owns Magic Springs, and has plans to build a park in Nashville, Tennessee.
In 2002, the company made a bid for Visionland, a theme park in Alabama, but the price was too high. Themeparks LLC and Adventure Parks Group have talked about a merger, but nothing has yet developed. The company's main office is in Louisville, Kentucky.
In 2010 the company formed KK Redevelopment LLC to buy back Kentucky Kingdom from the state of Kentucky.
