'Championship Manager' is the world's fastest-selling PC game, having already sold 4m copies worldwide since launch. Players get to experience the highs and lows of football management on their PC.
The new edition for the 2003/04 season will be available from the end of November 2003.
Ric Williams, head of marketing at Eidos, said: "'Championship Manager' has an incredibly loyal following and our challenge now is to widen the game's appeal by attracting new football-loving fans. We have appointed Billington Cartmell on the strength of its strategic and creative understanding of our consumers and their relationship with football."
Billington Cartmell recently developed a global ad campaign for Carlsberg, to support its club sponsorship of Liverpool FC.
The agency is responsible for all UK exploitation of Carlsberg's England and FA Cup sponsorships and is also responsible for the Lucozade Sport promotional association with Michael Owen.
