The PlayStation 2 was in development for some time before it was revealed to the public in April 1999. The PlayStation 2 is a very powerful console that can handle millions of polygons per second, making graphics more life-like. Added to this is the "Emotion Engine" that can simulate weather, worlds, human behaviour and emotions, so that games will react to players' actions in a more realistic way.
The console can play two media formats: CDs and DVDs. PS2 games are stored on DVDs which can hold 3.2 gigabytes or 6.4 gigabytes if dual layered. This means games can be much larger than ever before. You can also play DVD movies (a remote control can be bought separately but is not required), music CDs and the PS2 is backwards compatible with original PlayStation games. The PS1 games will sometimes even show some improvements in graphics and loading times.
All these factors contributed to the Sony PlayStation being very popular.
