People are tired of a continual diet of negativity.
To be sure there is the occasional frisson of interest in some attack on someone or something but that is against a declining background of interest. Advertisers are beginning to realise that advertising in a generally negative publication also has a negative effect because the mood affects the advertising message. Perhaps because journalists see themselves as brave crusaders exposing the faults, corruption and pretensions of society. I believe the answer is very much simpler. I had thought it was enough to invent the terms 'jott' and 'jolt'.
