There's a German philosopher called
Theodor Adorno who seems relevant here; he wrote a lot about the difference between "high culture" and "low culture" in the 1960s, and is generally talked about as if he absolutely despised popular culture, but it's worth pointing out his earlier works dealt more with the method of delivery than an elitist stratification of culture itself. There's a quote referenced in his Wikipedia page that says it well: "The meaning of a Beethoven symphony heard while the listener is walking around or lying in bed is very likely to differ from its effect in a concert hall where people sit as if they were in church."
I think that's both the root of the TV and Internet issues here. Regardless of their socio-economic background, it seems that the less effort people have to put in, the less they value the result (or the thing they consume). That's what's really fuelling the "race to the bottom".
Someone else mentioned Usenet; I've been thinking a lot lately about "
eternal September", or the changing of Usenet's culture when Usenet access was bundled in with AOL accounts, flooding the service with non-techy users. That basically defines the entire internet for me: while Web 2.0
et al. claimed to be democratising the internet, reducing the barriers to entry (or, more accurately, creation) just flooded the entire web with low-effort, poorly-thought-through noise with no curation. And people saw this as a get-rich-quick scheme, monetising it through one idea or the other (YouTube ad revenue, paid influencers, crypto, etc.) while simultaneously trying to find ways of doing it faster and faster with less effort (leading to the GenAI-created slop that is overwhelming every space on the internet now).
Same thing's happened with news: people don't read any more. They don't study. They don't take time to understand. They just want it fast and easily consumable. And companies and corporations want to give them that, because it's quicker and costs less for them to make while bringing in more money.
I don't know how to undo that rot, but making the whole thing more difficult again might be a start.
