With the inaugaration of President Barack Obama and the convening of the U.S. Congress, the business of governing truly begins in earnest. With the business of governing, comes the creation and passage of legislation and policies that affect important constituency groups. Some of the most powerful constituency groups are those that represent specific industries that employ hundreds of thousands of Americans. The “trades” that these associations represent vary from sectors such as high technology to small business to health care and energy.

With the widespread adoption of social media by elected officials, the media and the public; social media has become a critical part of the advocacy toolkit for trade associations. The recent legislative battle over the SOPA bill between the Motion Picture Association of America and the technology industry highlighted the evolution of tactics in advocating for or against legislation. The Motion Picture Association of America pursued traditional lobbying tactics, while the technology industry mobilized their grassroots supporters via social media and the internet. The technology industry’s victory over the Motion Picture Association of America last year sent shock waves through the K street community that they must evolve and change.

How have they done? Arc 3 looks at the top ten most social media savvy trade associations at the start of 2013. The list was compiled analyzing the Klout scores and number of Twitter and Facebook followers for the largest and most powerful trade associations in the country.
