Stephen Moore is departing Aardman Animations to become a partner and shareholder of children's programming company Abbey Home Media.
UK-based Abbey Home Media works on franchises including Horrid Henry, Sesame Street, Paddington Bear and The Magic Roundabout.
Moore is also a veteran of 20th Century Fox.
He said: 'Since coming back to London from Los Angeles I have had a real desire to become a stakeholder in a business with the pedigree and track record of Abbey. Anne and Ian have built a very special company over the last 20 years and I intend to retain its essential values while building a new creative platform. My experience with both Fox and Aardman has put me in a very strong position to help take Abbey on to the next level.'
