Sony’s PlayStation 2 has had a remarkably long life for a home video game console. Released in 2000, it has sold over 140 million units. In Japan alone it has sold over 21 million units, and game developers continue to release new titles, even after Sony debuted its next-generation PlayStation 3 in 2006.

The times are changing, however, and handheld consoles are more and more often becoming the chosen platform for game developers.

By offering games that casual users are interested in, such as "brain training" games and cooking games, the Nintendo DS, released in 2004, has already surpassed the number of PS2 units sold within Japan for a total of 30 million consoles, or one for every four people in Japan. In turn the huge success of the console has attracted game developers who covet the large market.
