Licensing company Chorion specializes in turning literary works into revenue-generating brands. The company develops and manages intellectual properties from such literary estates as Agatha Christie and Raymond Chandler. Its children properties include brands such as Beatrix Potter, Paddington Bear, Mr. Men, and Olivia. Chorion explores licensing opportunities in television and audio as well as licensing for continued publishing for its literary properties. An investment group led by company management and backed by buyout firm 3i took Chorion private in 2006. After years of being weighed down by a substantial debt load, Chorion filed for administration in 2011 and has put itself up for sale.
