And we've mostly hit the limit of usable maximum sizes. For like the last two decades you could upgrade your TV to the next bigger size every few years for the same money you paid for the last one.
I remember starting with a maybe... 21" LCD TV back in 2005ish, and for that money today I could get like 70" TV.
I don't have space to fit one that large, nor do I have any need for it even if I could.
