The now high-profile billionaire brothers, Charles and David Koch, are not only major funders of conservative causes and candidates but also exert significant influence over media outlets and public opinion generators.
In June of 2010, the Koch brothers, who together own the second largest privately held company in America, held a conference in Aspen to plot strategy for the November 2010 elections. The list of attendees was leaked, revealing some interesting ties the Koch brothers have to the mainstream media.
The Sierra Club, the oldest and largest grassroots environmental group in the United States, has launched a social media campaign targeting Koch Industries, the second largest privately held company in the nation according to a 2010 Forbes ranking.
In an effort to increase public awareness of what it alleges are environmental transgressions by the industrial giant, the organization has called on its 1.4 million members to take to social networking services such as Twitter and Facebook to express their sentiments and "dislike" Koch Industries.
"The Kochs have a lot of money, which they are using to try and buy our government and undermine common sense protection of clean air and water," said Rachele Huennekens, a Grassroots Media Coordinator for the Sierra Club. "We can't match them in terms of resources, so we have to turn to the passion of our supporters."
