Ps2 came out less than 5.5 years after PS1.
Ps3 came out over 6.5 years after PS2.

This gave ps2 an unusually long period for success and support. Combine that with the fact that PS3 wasn't very popular at launch due to price and it gave PS2 even more legs.

People celebrate the PS2 like it achieved this great thing but in reality it smothered its own parent to death slightly ahead of schedule and was stepping on it its offspring to maintain it's position. Did it sell great on its own? Yes. But it wouldn't be number 1 all time if not for the reasons above.

As well it literally had no competition in the home console market.
