This does not bode well for advertising in this media so you will likely continue to see a downward spiral in the quality of people who view television and increasingly, sponsors will opt for other media so that they can target more affluent consumers.
This cannot happen soon enough as I think the programmers of television have already sunk to the lowest common denominator. After a while, even the Taco Bells and Budweisers of the world will find this remaining audience not worth their advertising dollars.
Tv is basic for many for the variety ... sports, cooking, travel, religious programs, weather, news, ... Sorta like the radio is still going after all these years. Wrestling is still going strong (who knows why) as is NASCAR, Some of these people have a lot of money, buy lots of beer, smoke cigarettes, use laundry detergent, buy Automobiles, P C's, etc.
Many of the recent movies are not worth renting ...stupid inanity or bias.
You may be sounding the death call too soon.
