W. Joseph Campbell — news media myth buster — has the facts:
The myth holds that people who watched the debate on television thought that Senator John F. Kennedy won; those who listened on radio thought Vice President Richard Nixon had the best of it.
The myth was long ago debunked by scholars David L. Vancil and Sue D. Pendell, in an article in Central States Speech Journal. They noted that reports of viewer-listener disagreement typically were anecdotal, and the few surveys that hinted at a viewer-listener disconnect were too small and unrepresentative by which to make confident judgments.
