I just came across a great study co-produced by FedEx and Ketchum, titled The 2012 FedEx/Ketchum Social Business Study

This study, updates and expands upon research first undertaken in 2010 and analyzes the changing impact of social media on business today.  To quote, “Organizations are leveraging social media tools to evolve into social businesses – creating communities and relationships with external and internal stakeholders that are transforming the way they do business.”
