Carnival Films

Background
Carnival Films is a British production company which was founded in 1978 as Picture Partnership Productions by feature film producer Brian Eastman. It was later renamed to its current name in 1988. The company produces feature films and programs such as the long-running series Downton Abbey and The Last Kingdom. In 2007 the company was sold to Australian company Southern Star Entertainment and was later acquired by American-based media company NBCUniversal (who owns Universal Television) in 2008, marking its first UK acquisition and adding the company into its international portfolio. Prior to 2002, the company had no on-screen logo and used in-credit text notices at the time.
