Probably has to do with market fragmentation. Fox News is the only broadcaster on cable remotely trying to cater to “right leaning” Americans. Whether they actually do is an open question but that’s the perception. Meanwhile CNN, MSNBC, ABC, CBS, NBC etc all compete for the same ideological base. So that market is fragmented. The other networks are basically interchangeable with 90% of their content coming from the same talking points and the same “anonymous sources”.
I’d like to see how Fox compares to all other cable news programs combined.
Newsmax is good but you have to pay for some of it..
