By year, league average has been going up and up (listing every 5 years to show the trend):
2024/25 37.5 3PA
2019/20 34.1 3PA
2014/15 22.4 3PA
2009/10 18.1 3PA
Going a step further, I graphed out 3PA as a % of total FGA since the 3's inception in the NBA. (That brief spike in the 90's is when the NBA shortened the 3P line for 3 seasons).
The trend of taking more 3's has been gradually going up since the beginning (but starting growing a little more rapidly at the same time Steph started taking off). Will this keep growing? Eventually it has to plateau though, but what point is that? Every year for like the last 10 has felt like we're probably at the peak.

With this I think it's kind of interesting though to look at the change in shooting percentages (or in some cases lack thereof).

Despite the increase in attempts and more focus 3's, the overall league 3p% has largely stayed flat at ~35% for the last 30 years.
And 2p FG% has only started to climb over the last 10 years (it was right under 50% for 35 years, then has started to climb over the last 10).
But the balance of overall FG% has roughly stayed the same, in that 45-49% range throughout. If teams are making the same amount of shots as they always have, does it really matter where it's coming from (from a fan enjoyment perspective)?
Complaining about 3's is just the low hanging fruit though when trying to explain TV ratings, which I think would be down no matter what.
