Sony only reviewed electronics in select markets, not including the business that IPG's UM supports in North America and India
The move to review both mobile and electronics came on the heels of an organizational shift within Sony Corp. In 2011, the company announced plans to acquire Ericsson's shares of mobile group Sony Ericsson. A year later, the Sony Ericsson group became a wholly-owned subsidiary of Sony Corp.
Omnicom's PHD won the Sony Ericsson mobile business from WPP's MEC in summer 2011. The agency did not defend the mobile business, now under the Sony Corp umbrella, in the recent review, industry executives told Ad Age.

Sony spent a total of $1.04 billion on U.S. media and promotions in 2011, according to the Ad Age DataCenter. In 2012, Sony Corp, including all of its subsidiaries, spent a total of $724.9 million on measured media in the U.S.
