Zenith Entertainment

Background
Zenith Entertainment was a production company that was founded by Charles Denton as a subsidiary of Central Independent Television. In 1987, Zenith was sold off to Carlton Television in 1987, and became a production company on its own. Carlton sold a 49% stake to Paramount Pictures in 1989, and had bought out Action Time Productions, which was then folded into Zenith. When Carlton took on the ITV franchise in 1993, it sold off Zenith, while Action Time was sold to its management, and the drama side was sold to Portman Entertainment. It was then merged with Television Enterprise & Asset Management, and then renamed into Zenith Entertainment. In 2003, it was sold to its management, and it was defunct in 2006. In 2016, the rights were purchased by Simply Media TV.
