Not sure what point you were trying to make here. The public in general reacts to higher channel count as value added. Traffic cams, 24/7 weather, doesn't matter. Someone likes them.
At least in my DMA, over 75% of the subchannels are devoted to these nostalgia content networks. Antenna, H&I, Decades, Grit, etc. And it seems that they prefer to see reruns of Barney Miller more than they care about the network feeds being razor sharp.
A story to relate. Several years ago, I had cable installed. I specified an HD feed and an HD DVR. I was at work, so my kids were there for the installation. When I got home I noticed it looked like garbage. It didn't take long to figure out that the installer had ignored the HDMI cable I had left and connected the DVR via an RF feed tuned to channel 3 (NTSC). I called Charter and complained. The tech sympathized, but then stated that most people were unhappy when they connected the HDMI cable were required them to switch to the HDMI input. They were used to tuning to channel 3. Basically, the average person never noticed the difference and just wanted stuff to work the way it always did. Thus wasting features of a new TV and an upgraded cable box.
Face it, we are not the normal viewer.
