Why does FOX News do so well?

Despite perpetual lambasting from the left, the numbers speak for themselves.

Among all basic cable networks in 2013, FNC ranked sixth in primetime while MSNBC was 29th and CNN was 31st. In total day, Fox ran fourth while CNN was 28th and MSNBC ran 30th.

Fox News Channel averaged 1.774 million viewers in primetime  followed by MSNBC with 645,000 viewers,  CNN with 578,000, and HLN with 403,000.
