As of July 1, 1999 Graham Ralph is relinquishing his stake in London-based Hibbert Ralph Animation, which will then be known officially as HRA. This will enable Ralph to invest actively in future films and TV series' through a new company, Silver Fox Films. He will also be acquiring the rights to Hibbert Ralph Entertainment's library. Jerry Hibbert and Kim Burdon, who have worked together since 1983, will continue to develop HRA as an animation production company servicing the advertising industry, and will also continue to invest in new technology through their in-house computer animation facility, HR3D.
