Comcast has placed its media duties in review to consolidate its U.S. media business, reports AdWeek (via MediaBuyerPlanner). Media duties currently reside with in-house resources and several agencies. The review is being handled by Pile and Co. Comcast's lead creative agency is Omnicom Group's Goodby, Silverstein & Partners, which will not be affected by the current review. Comcast spent $225 million in paid media through September 2005, according to Nielsen Monitor-Plus.
