Well, there's at least a few reasons this is different than the current situation.
1) It's expensive to make a TV show, it's free to do a fortnite dance or eat a tide pod and post it to several websites. The amount of low-effort, low-quality, probably-harmful content on TikTok or whatever is exponentially more than low-effort, low-quality, probably-harmful TV shows/ads.
2) The availability is on completely different scales. TVs are (basically) fixed in a specific place. Phones are, for most people, within arms reach 24/7.
3) What can be shown on TV is significantly more regulated in most parts of the world, and control mechanisms by governments are more robust (pull a broadcast license, etc.). It's harder to take a website (or TikTok, whatever) offline than it is to pull a harmful show/advert off of HGTV or whatever your favorite channel is.
4) TV is not specifically tailored to the viewer to produce the most amount of happy chemical.
And in fairness, dosage is the difference between a painkiller an a heroin addiction.
So why are we surprised that when we put a TV in the kids' hands things got even worse? Meta testified on the stand recently that they're not a social media company anymore, they're now all about video. Tiktok is the new TV. Every app wants to Tiktokify. The money from TV, just pushing an endless stream of video to someone, is very good.
We were able to go back to one TV in the house (at least I was), and even avoid a big chunk of the ads when watching TV (by paying for Netflix/etc) and even radio (Spotify/etc).
Except we now we put a garbage TV in every hand.
It's a terrible idea because it's a tiny screen; because it's not a shared experience, but an isolating one; because it's been proven that it's bad for eyesight/myopia. But most of all, it's terrible because the content is crap.
Spending hours watching a never ending sequence of low effort 2min videos that need to deliver on the first 30s (or they're skipped) is not the way to make anyone smarter/saner.
Australians are very aware that it destroys people’s brains.
I would argue that it did, we just did a poor job of measuring it.
Anecdotally, during my childhood I moved from a place that had very little TV advertising to a place with a normal amount and it had a noticeable impact.
Same shit, new generation.
The algorithms create the engagement, the engagement lures in the ads, not the other way around, at least that's what I think right now.
