The £9 million ($12.8m; €14.7m) British media duties of Clear Channel Entertainment - a unit of Clear Channel UK, itself part of America's Clear Channel Worldwide - are being reviewed.

CCE wants to merge the advertising strategies for its music and theatre operations, and has reportedly launched the review to discover whether the consolidation of its media business within one agency will save money.

Incumbent on the creative and media buying duties for the music division is Sold Out, with the theatre unit in the hands of McCabes, Dywynters and Haymarke.

CCE also wants to "make better use" of its parent's outdoor media assets - such as More O'Ferrall, Adshel and Taxi Media - to improve the brand sponsorship strategies it can offer clients.
