During 2009, Twitter surpassed blogging as the social media platform of choice – at least among the Fortune 100.

A recent analysis compiled by Burson-Marsteller and Proof Digital Media found that the largest 100 companies, in the terms of revenue as compiled by Fortune Magazine’s annual Fortune 500, were active on three key social media: Twitter, Facebook and Blog. 

According to the study, 54% of the Fortune 100 use Twitter to reach out directly to stakeholders,while 32% use blogs and 29% actively use a Facebook Fan Page to engage. Despite the perception that Twitter is the newest kid on the block among the three platforms, 76% of Fortune 100 companies that were using just one social media channel were using Twitter over the other two channels.

The study also revealed that that Twitter is most often used for news and announcements (94%), customer service (67%), promotions and deals (57%), and job postings (11%). By contrast, Facebook fan pages are more consumer focused, with promotions, product information, and philanthropy and community service announcements. And content on corporate blogs, the study found, falls into categories of current projects, external initiatives, and community involvement.
