The Center for Marketing Research at the University of Massachusetts Dartmouth recently conducted a new in-depth and statistically significant study on the usage of social media in fast-growing corporations. This new study revisits the Center’s study of Inc. 500 social media usage for the third consecutive year, making it a valuable and rare longitudinal study of corporate use of these new technologies.

The new study compares adoption of social media over three years (2007, 2008 and 2009) by the Inc. 500, a list of the fastest-growing private U.S. companies compiled annually by Inc. Magazine. For details about the 2009 Inc. 500 and the complete directory of the included companies, please visit Inc. Magazine’s website at www.Inc.com.
