There is no ideology on beer. Oddly, in the DC area, both the left and the right has been selling ads in the Governor's race. The ad content has little to do with who owns the networks. The public owns Frontline as part of PBS, which shows that truth has a left wing bias. Of course, there could be right wing shows on PBS, it is just that the right does not offer them because they don’t like the concept. Actually, news is kind of civics. FoxNews was possible from Fox media, the raunchiest collection of movies, music and TV allowable in the pbulic space. NBC was bougth by GE and then Comcast (porn anyone?)/ ABC is owned by Disney and I forget who owns CBS. They make their money separately, not by ads and the capitalists occassionaly intervene to kills stories that come clsoe to home, but all but Fox are mostly independent.
