It's the most-watched cable channel, but it's only watched by a tiny fraction of the population. MSNBC and CNN also rank highly relative to cable channels (below Fox and ESPN and above HGTV) but are still very low in terms of overall viewership. Kind of like Twitter, which has 37 million "monetizable daily active users" in the US, of which about half of them use Twitter daily. So that's something like 19 million users - high for a social network or web site, but still a tiny fraction of the population.
