It's not just TV, it's the whole social media thing too. This includes all those supposedly less harmful alternatives like Youtube, 4chan, Reddit, Mastadon, Twitter and Hacker News are all poisoning your mind and there is absolutely nothing you can gain from it. Just delete all your accounts there and never look back, because if there is anything noteworthy happening, you will notice it inevitably, maybe 1 month, 2 months or half a year later, but you will still hear about it somewhere. In particular for Youtube and 4chan, some people try to find excuses, why they actually need it and so on, but in reality it only makes you anxious, depressed and braindead. If you are particularly news-addicted, you can still subscribe to some RSS-Feed about things, that interest you, but everything is better than that.
