i don't know a single person with cable, not a single one that watches traditional tv. What are tv ratings supposed to be indicative of? that folks who grew up watching tv aka boomers are dying off?
When I grew up we had a black and white TV and got four channels and rabbit ear antennas. There was no remote, so you changed the channel by turning a big knob. I enjoyed that television more than I do Netflix today on a 32 inch flat screen color television. I haven't had cable for a while, I just watch Netflix.
I think what you mention is part of the problem for Trevor Noah. His audience is a young demographic. Most young people stopped paying for cable long ago. I'm not even sure what they've moved onto.
