From MediaBuyerPlanner.com:

GM, in what could signal a no-look-back shift to digital marketing, will dedicate half of its $3 billion budget to digital and one-to-one marketing in the next three years.

As the country’s third largest advertiser, GM’s switch may be the online marketing shot heard round the automotive world. GM, which spent nearly $10 billion on advertising last year, will use several online methods including gaming, search, mobile and a broad array of interactive applications.
