There is a documented history of FoxNews having shareholders and CEOs with a direct conservative agenda.

There is NO documented history of any other news network in the country having shareholders or CEOs with any direct political agenda. None. Zilch.

A news network CEO referring to a political party as "the other side", as Roger Ailes did, is evidence of propaganda. You're just not going to find evidence of any other network having leadership with this kind of agenda.

Ailes was with Fox from the start, which was in 1996. This network has served as conservative political propaganda from that very day, and continues to up to this very moment.
