92% of the 2012 Inc. 500 companies use social media, ranging from popular tools such as LinkedIn (81%), Twitter (67%) and Facebook (67%) to emerging ones, such as foursquare (28%) and Pinterest (18%), according to a study released in January 2012 by the Center for Marketing Research at the University of Massachusetts Dartmouth. Interestingly, though, when executives from these fast-growing companies were asked how necessary social media has been for their growth, about 4 in 10 responded that social had been “somewhat” (24%) or “very” (15%) unnecessary.
