I was lucky enough to see this in a Media Studies class. Great documentary.
Though, it doesn't really do much to dismiss the allegations that the media's predominantly liberal. It certainly makes (more) evident the right-wing bias at FNC, but it doesn't go into detail with other networks, allowing "FOX Fans" to claim that the channel's bias is there to balance out the media.
I wish that they had compared CBS along with PBS and FNC when they showed some of the results of
this study.
