Earlier quoted context omitted.
Fortunately, corporations are pretty shitty at deliberately pushing a cultural agenda. I dare you to find a consistent agenda in any media conglomerate's output.
Sarcasm? I can think of one... EDIT: News Corp was what I was thinking.
EDIT: Despite Fox News, the Fox network broadcasts left-leaning shows like The Simpsons, Family Guy, and American Dad, which regularly mock Fox News. 20th Century Fox distributes a lot of films without any discernable agenda[1], even backing films like Avatar, or the Wall Street sequel. I'm convinced that News Corporation is entirely mercenary in its agenda and only started Fox News because right-wing cable news was a wide open opportunity in the late 1990's.
