Kathleen Hall Jamieson and Joseph Cappella-two of the nation''s foremost experts on politics and media-offers a searching analysis of the conservative media establishment, from talk radio to Fox News to the editorial page of The Wall Street Journal. Echo Chamber is the first serious account of how the conservative media arose, what it consists of, and how it operates. Jamieson and Cappella find that Limbaugh, Fox News, and The Wall Street Journal opinion pages create a self-protective enclave for conservatives, shielding them from other information sources and promoting highly negative views toward conservatism''s political opponents. A thoughtful and incisive study, Echo Chamber offers the most authoritative and insightful account of this revolutionary phenomenon and its indelible effect on the American political landscape.
