"Gallup first measured trust in the mass media in a 1972 survey when 68% of Americans said they trusted it. Similar levels were recorded in 1974 (69%) and 1976 (72%), but two decades later, when Gallup next asked the question, trust had fallen to 53%. Although overall trust was at the majority level until 2004, no more than 21% of Americans dating back to 1972 ever said they had the greatest level of trust. Currently, 13% have a great deal of trust, 28% a fair amount, 30% not very much and 28% none at all."
