I also agree with you Indu Mam, whenever we go to listen the news or if we read in the newspaper, it is mostly related to murders, big crimes, theft, harassment in many forms and a lot more. This is the reason I do not prefer watching news. Because there is a lot of negativity spread all around. Media tries to figure out everything in a complex manner. They never focus on positive aspect of any topic.
Is it because even people like to read and watch such sadness or are they really effected by this? Even my father watches news most of the times, and at max, it gives negative impact, some or the other times it is related to elections or so. It is really because people are more negative today rather than being positive. Or we can also say that it is the era of "Kalyug" - when the elders , our grandparents used to teach us that there will be more of blood spread around in these times and people will keep doing sin at every single moment.
A positive attitude will lead to positive results.
