The World: New York - CBS calls review of its $130m media business

CBS is reviewing its $130 million media planning and buying account.

The move follows the broadcasting giant's split with Viacom earlier this month, Carat, the incumbent, has been asked to repitch for the business.

With the split from Viacom, CBS has added extra media assets to its portfolio of businesses, including Showtime, King World, Paramount and Simon and Schuster Publishing, all of which will be part of the review.
