AIM helped “create the image of the mainstream media as very liberal,” according to Alex S. Jones, the director of the Shorenstein Center on the Press, Politics and Public Policy at Harvard’s Kennedy School of Government. The New York Times described AIM as “dedicated to exposing, challenging, and at times bullying” news organizations.

AIM’s founder Reed Irvine was previously an economist with the Federal Reserve. 10 While at the Fed, Irvine led luncheon discussions for the International Economists Club and the Arthur G. McDowell Luncheon Group. The discussion topic for one of the 1969 luncheons was perceived bias against the Vietnam War by the television nightly newscasts. 11 At this 1969 discussion, Irvine, then 50, hatched the idea for Accuracy in Media.

Accuracy in Media (AIM) has grown from a one-person crusade to a million-dollar-a-year operation by attacking the mainstream media for abandoning the principles of "fairness, balance and accuracy" in its reporting. New Right philanthropies, think tanks and media support its work, and many members of its advisory board are former diplomats, intelligence agents and corporate directors.
