The media, and especially the press, are usually full of negative news: murders, attacks, economic failures etc. It may be that experience has indeed shown that negative matters are of more interest to readers. Even if this is so, I believe that at least one page of positive news would be welcomed by readers. Readers would turn to this page - even if they found the negative stuff more interesting.
Editors might agree with me. Then they would ask where positive stuff is to come from. Negative stuff comes easily from the police or the law courts. But where is the source of positive stuff.
So my suggestion is that someone sets up a 'Positive News Agency'. This would be a news agency like Reuters. It would collect positive news and make it available on demand.
