Really since the PS1 era. A lot of people were just happy to see the "giant" fall. PS1 was the system, Dreamcast was the unappreciated genius, and the N64 was mostly considered awful outside a few first party must haves.
Which is basically every Nintendo System since then as far as your average super involved internet user goes.
It's also when the Nintendo consoles stopped getting multiplatform games. the Cartidges were a big reason and it just continued from there.
