Bristol-Myers Squibb has placed its media assignment in review, according to sources.
The company spent $170 million on measured media in 2008, according to Nielsen, slightly down from the $175 million it spent in 2007.
The incumbent on the business is WPP Group's Mindshare, which is defending, per sources. Other contenders are said to include Interpublic's Universal McCann and Havas' MPG. The agencies either declined comment or referred questions to the client.
Mindshare won the business in 2001 (when the client reportedly spent $275 million annually on advertising) after a review. Previously, the company had handled its media planning and buying internally.
A client representative could not immediately confirm the review.
The company reported close to $21 billion in sales in 2008. It identifies its top selling brands as Plavix ($5.6 billion), Abilify ($2.2 billion), Avapro/Avalide ($1.3 billion), Reyataz ($1.3 billion) and Sustiva ($1.1 billion).
