According to an article by the "Harvard Business Review", "Fifty-eight percent of companies are currently engaged in social networks like Facebook, microblogs like Twitter, and sharing multimedia on platforms such as YouTube."  The Harvard Business Review cites an additional 21% of companies as being in the process of implementing a formal social media initiative.
