Micheal Medved ( who is Jewish) said it's pretentious to say Jews do not have control of the media apparatus in America.

I doubt very much he has said that. But, more to the point, could you define "control," please?
It is clear that, since the World War II, Jews and those of Jewish decent have visible presence in our culture. Is mere presence in something also control of that entity? If not, what is?

For more I would recomend Thomas Sowells Race and Culture.
