Maybe late 90's. 80's Home computers were fairly expensive if you adjust for inflation and media was limited (and far from instant. Oh, the dial-up days where even saving a Gamefaqs guide could take minutes. Can only wonder how the early 90's went). In addition, it was much cheaper than today to go out on a bar crawl or even the arcades.
But i think we both agree entertainment got cheaper while outside life more expensive. We can grab internet connected devices for barely $100 and a single entertainment subscription (Netflix, Gamepass, Spotify) is maybe $10/month for an entire catalog. I can't even go out for lunch for $10 unless I do Costco.
