Modern game multimedia usually comes in the form of an disc, which can be inserted into the game console. Recent advances have allowed games and game demos to be downloaded directly to the console via the Internet. Simpler consoles, however, may only have a fixed selection of built-in games. Cartridges were previously common storage devices for video game data, but due to technological advances, most video games are now stored on CDs, or higher capacity DVDs, or the Blu-ray Disc used by the PlayStation 4 and Xbox One. The only games stored on cartridges now are the ones for the Nintendo DS, Nintendo 3DS, PlayStation Vita, and Neo Geo X and they are called "cards".
