A new study finds that the use of social media by those active in political causes is growing, even more than in the past.

Forbes.com reports on a new survey by Burson-Marsteller, a public relations and communications firm, “that looks into how political advocacy groups--which largely determine the discourse and direction of national policy debates--are using social media. The study found that 33 out of 34 political advocacy groups examined use at least one social media platform to engage their stakeholders.”

It adds, “Most of the nation's most influential advocacy groups, including the National Rifle Association, AARP and MoveOn.org, have embraced social media to reach, organize and mobilize their supporters to influence federal legislation and regulation. There is no shortage of lessons for business in what these groups have done."
