Kimmel has about 2 million viewers nightly. At his peak, Johnny Carson was drawing 15 million viewers nightly...in a country with 100 million less people than today. So, these late night comedians today can survive with a very niche audience of loony leftists. His viewers are probably the same people that watch Rachel Maddow. Times have changed, the late night comedians do not have near the influence of yesteryear.
