In many of the social media presentations I've given to public and private groups, I've referenced the social media usage surveys completed by global public relations firm Burson-Marsteller.

One week ago, the firm updated its look at the usage of social media by Fortune 100 companies. There are a few interesting stats worth noting:

  • There was a 25% increase in the number of Fortune 100 companies using the four major platforms researched (Facebook, Twitter, YouTube, corporate blogs and microblogs).
  • Twitter is emerging as the predominant social media platform used by corporations.
  • The average number of followers per corporate account increased 241% in the last year.
  • 36% of corporations maintained blogs.
