Guess who said it, and in what year:
“Political campaigns can be actually taken over by the ‘public relations’ experts, who tell the candidate not only how to use TV but what to say, what to stand for and what ‘kind of person’ to be. Political shows, like quiz shows, can be fixed — and sometimes are. … Whether TV improves or worsens our political system, whether it serves the purpose of political education or deception, whether it gives us better or poorer candidates, more intelligent or more prejudiced campaigns — the answers to all this are up to you, the viewing public. Without your approval, no TV show is worthwhile and no politician can exist.”
No fair if you use a search engine, like Google.
The answer is John Fitzgerald Kennedy. He wrote this in a column that ran in TV Guide in 1959, a year before he successfully ran for President.
