The ex-president of the CBS Network Television Group who’s now a CBS Inc consultant has become a non-executive director of the UK’s largest group of independent production companies. Tellem joins All3Media at an interesting time. The company is the last big independent UK TV producer left on the market. It’s expected to be sold next year to either a Hollywood studio anxious to get more into global TV production — such as Time Warner or Sony – or Brit broadcaster ITV, which needs to beef up its in-house production. Financiers I’ve spoken to expect the price tag to be around £500 million ($788 million). All3Media produces Undercover Boss for CBS and Skins for MTV.
