Downloadable content

Downloadable content (DLC) is additional content created for a released video game. It is distributed through the Internet by the game's official publisher. Downloadable content can be of several types, ranging from aesthetic outfit changes to a new, extensive storyline, similar to an expansion pack. As such, DLC may add new game modes, objects, levels, challenges or other features to a complete, already released game.

In the case of episodic video games, a new episode may come in the form of downloadable content, whereas music video games utilize this media to offer new songs for the players. Downloadable content became prevalent in the 21st century, and especially with the proliferation of Internet-enabled, sixth-generation video game consoles. Special edition or Game of the Year re-releases of games often incorporate previously released DLC along with the main title in a physical package.

The earliest form of downloadable content were offerings of full games, such as on the Atari 2600's GameLine service, which allowed users to download games using a telephone line. A similar service, Sega Channel, allowed for the downloading of games to the Sega Genesis over a cable line. While the GameLine and Sega Channel services allowed for the distribution of entire titles, they did not provide downloadable content for existing titles.

As the popularity and speed of internet connections rose, so did the popularity of using the internet for digital distribution of media. User-created game mods and maps were distributed exclusively online, as they were mainly created by people without the infrastructure capable of distributing the content through physical media.
