Regarding Brexit, I got so fed up with all the media spin around it, that I set up a TVHeadend[1] server on my network, and started watching (rather listening to while I work) BBC Parliament live via a small window on my screen using VLC. Once you start hearing the de-facto source for news events, it's amazing how brazen the mass media are in the manipulation of how they reported those events to support their own agendas.
I've been doing this now for about 1 month, and although some of the coverage is mundane, most of it is quite interesting. It's also good as background 'noise' as I work from home, which can be too quiet at times.
For technical news, I follow HN, and a few other sources. I tend to cross reference the reporting and try to see through the manipulation.
Beyond technical and political news (both of which can affect me directly), I no longer have an interest in other more 'general' news. Sure, an earthquake in Indonesia may be newsworthy for example, but as it doesn't affect me directly, why waste my time with it?
We've all been conditioned to suck up all world news as if it is important - Most of it isn't, and only exists to fill airtime and/or sell adverts. Calculate how much time it takes for you to consume your daily news, and then ask yourself if that was time well spent. My guess is that it probably isn't.
Finally, depressing news sells, and good news doesn't. People want to feel that they have a better life than the sad people shown on the news. The same thing goes for Soap Operas, they trade on this effect to keep viewers. In fact the absolute reverse happens - over time, people get more depressed watching depressing news, than they would if they didn't. The effect is more pronounced in people who 'catch up' on the news just before bedtime.
