RTL Group is upping Tony Cohen to chief exec of its production business, while managing direction Bruno Chauvat will take over the duties of Richard Eyre, who is ankling at the end of the month.Cohen is chief exec for worldwide production at Pearson Television, the TV division of media group Pearson, a 22% shareholder in RTL. Eyre was RTL’s London-based director of strategy and content as well as chief exec of Pearson TV. He held the post for 14 months. A spokesman said he was leaving on “amicable” terms. Eyre is the second major British exec to exit RTL since the group was created by the merger of CLT/Ufa and Pearson TV a year ago. A source said Eyre felt it was time to move on after the successful integration of RTL’s components.
