Second Life avatars
From time to time, I’ll give an overview of one broad MediaShift topic, annotated with online resources and plenty of tips. The idea is to help you understand the topic, learn the jargon, and take action. I’ve already covered blogs, social networking, widgets and various other topics. This week I’ll look at the growing phenomenon of virtual worlds.
Background and History
Virtual worlds are online three-dimensional spaces where you can interact with other people, collect items and build structures, and communicate via a virtual representative of yourself called an avatar. These worlds have been influenced by various science fiction writers such as William Gibson and Neal Stephenson, along with the movie, “The Matrix.”
Virtual worlds differ from massive multiplayer online games (MMOGs) because they don’t offer battles against monsters or have an overriding mission for players. For example, a resident of the virtual world Second Life might spend time in that space accumulating virtual land, rather than striving to complete quests or conquer levels as one would in many popular MMOGs such as World of Warcraft.
The origin of virtual worlds goes back to early games such as Maze War, which was developed in the early ’70s at NASA. The game included eyeballs as avatars, there were maps showing the levels, and it was one of the first games played on networked computers, and eventually over a precursor to the Internet.

Habitat scene
In 1986, LucasFilm Games developed Habitat, a more two-dimensional environment that included humanoid avatars, and people could access the game through online service Quantum Link on their Commodore 64 computers. Developers Chip Morningstar and Randy Farmer, who maintain a blog about their experience with Habitat, say they let Habitat residents generally set their own rules governing the world — as long as they couldn’t hack into the system. In a research paper about their lessons from Habitat, the developers wrote:
