>almost all houses up to even 2000 have popcorn ceiling in north america.
Bullshit, popcorn ceilings were a relatively small fad that died out by the end of the 1970s. I've lived in exactly one house that had them, and that was a short-term rental that was custom-built in probably the 1960s but maybe the 1950s by a weird old lady who thought she was an architect.
