what feature led to the most sales for the playstation 2
PlayStation 2 Announced in 1999, the PlayStation 2 was the first PlayStation console to offer backwards compatibility for its predecessor's DualShock controller, as well as for its games. The PlayStation 2 is the best-selling video game console of all time, selling over 155 million units, with 150 million confirmed by Sony in 2011.[10] More than 3,874 game titles have been released for the PS2 since launch, and more than 1.5 billion copies have been sold.[11] Sony later manufactured several smaller, lighter revisions of the console known as Slimline models in 2004. In 2006, Sony announced and launched its successor, the PlayStation 3.
Nintendo video game consoles Although the company had earlier released Color TV Game and Game & Watch, which were their first and second systems respectfully, they did not achieve worldwide success until the release of the Nintendo Entertainment System (NES) in 1983. The NES restarted the video game industry after the video game crash of 1983, and was an international success. In 1989, Nintendo released the Game Boy, which became the first handheld console to sell in large numbers. In the early 1990s, Nintendo's market lead began to decrease; although the 1990 Super Nintendo Entertainment System (SNES) was a strong seller, the Mega Drive/Genesis was a very strong contender. Nintendo and Sega would both lose a significant portion of the console market towards the end of the 1990s, as Sony Computer Entertainment's PlayStation became the most popular console, beating the Nintendo 64, though Nintendo managed to sell more than Sega Saturn.
