This document summarizes social media case studies for Starbucks and Ford Motor Company. For Starbucks, it describes their current situation focusing on gaining popularity through social media rather than traditional marketing. It outlines their social media presence on Twitter and Facebook, and how it helped boost their reputation and meet environmental stewardship goals. For Ford, it discusses their failed "Lion Man of Tanzania" viral marketing campaign on YouTube in 2007-2008 that was misleading and did not effectively promote their product. This led to negative consumer feedback and potentially hurt sales over that period. The document concludes that Ford would have benefited from better social media marketing.
