You must not be familiar with the concept of: gory makes the story, or if it bleeds, it leads news reporting.
Drama, death, bad stuff - all guaranteed to titilate and excite the masses - and sell time slots. More attention, more gossip mean more advertising, more money, more prestige for the reporters, all that jazz.
Heartwarming, happy feel-good things aren't fun for the reporters and generally aren't as fun to watch. So they're considered boring and don't get the news traction they should.
