Only NES , PS1 & PS2 were dominant.
For PS1 & PS2 it played a big role that cd & dvd format vs nintendo 64 cartidge & gamecube disc had more space availiable for many developers so it had many third party exlusives.
Also one big advantage for sony was that their consoles easily got hacked.
Sega was never a big competitor (only one exception megadrive).
