Media Discs Development

Cartridges…

Game cartridges consist of a printed circuit board housed inside of a plastic casing, with a connector allowing the device to interface with the console. The circuit board can contain a wide variety of components. All cartridge games contain at the minimum, read only memory with the software written on it.

Cartridges were the first external media to be used with home consoles and remained the most common until 1995 continued improvements in capacity.

Cards…

Several consoles such as the Sega Master System and the TurboGrafx-16 have used different types of smart cards as an external medium. These cards function similar to simple cartridges. Information is stored on a chip that is housed in plastic. Cards are more compact and simpler than cartridges; this makes them cheaper to produce.

Magnetic Media…

Home computers have long used magnetic storage devices. Both tape drives and floppy disk drives were common on early microcomputers. Their popularity is in large part because a tape drive or disk drive can write to any material it can read. However, magnetic media is volatile and can be more easily damaged than game cartridges or optical disc.

Optical Media….

In the mid-1990s, various manufacturers shifted to optical media, specifically CD-ROM, for games. Although they were slower at loading game data than the cartridges available at that time, they were significantly cheaper to manufacture and had a larger capacity than the existing cartridge technology. By the early 21st century, all of the major home consoles used optical media, usually DVD-ROM or similar disks, which are widely replacing CD-ROM for data storage. The PlayStation 3 system uses even higher-capacity Blu-ray optical discs for games and movies while the Xbox 360 formerly used HD DVDs.

Internet Distribution…

All three seventh generation consoles (the PlayStation 3, Wii, and Xbox 360) offer some kind of Internet games distribution service, allowing users to download games for a fee onto some form of non-volatile storage, typically a hard disk or flash memory. Recently, the console manufacturers have been taking advantage of internet distribution with games, video streaming services like Netflix, Hulu Plus and film trailers being available.

Microsoft's Xbox Live service includes the Xbox Live Arcade and Xbox Live Marketplace, featuring digital distribution of classic and original titles. These include arcade classics, original titles, and games originally released on other consoles. The Xbox Live Marketplace also includes many different hit movies and trailers in high definition, and is accessible with a Xbox Live Free Membership. There is also an "Indie Games" section where small time developers can buy a license and release their own games onto the marketplace.

Sony's online game distribution is known as the PlayStation Network (PSN). It offers free online gaming, downloadable content such as classic PlayStation games, high definition games and movie trailers, and original games such as flOw and Everyday Shooter as well as some games that also release on Blu-ray Disc such as Warhawk and Gran Turismo 5: Prologue.
