I studied psychology in school, so I know I read this but sorry for not being able to cite it: If you tell someone the same message over and over, they begin to believe it. I don't mean that in a cliche way, I mean literally and clinically. IIRC, the average you had to pad a message was 60 repetitions before it "sunk in" to someone. If anyone has a citation or the study, please, supplement this comment :) I'm not being so brazen as to say the media intends this effect. But I think humans know it exists on some level and have always exploited it.
