One of the worst things you can do for your mind is watch the eleven o'clock news. Before you head off to bed. Rarely do you see anything positive - it's all about calamities, accidents, and murders. And, of course, X product does something bad.
Clearly,when folks change the channel away from your program, your profitability goes down. So, you might do a bit of research to find out what tends to make folks change or not change the channel.
Your research could indicate that strong negative emotions, such as anger, sadness or fear tend to make the viewer fixate and not change the channel.
Finally, you might ask yourself, how should the news be presented so as to maximize profits?
In many cases, a news outlet's profitability is directly related to the amount of emotional distress it can generate in its viewers. Sure isn't something I want to support when looked at that way.
That doesn't make it okay or good or long termist.
