Media conglomerate InterActiveCorp announced several niche sites earlier today, including Green.com, a new virtual world site built to teach children and 'tweens how to help the environment and "do good deeds in fun ways."

IAC's online properties include search engine Ask.com, dating service Match.com, and virtual environment Zwinktopia. Like Green.com, Zwinktopia targets the middle school set, offering easily customizable avatars -- "Zwinkies" -- that can be exported and shared on blogs and MySpace profiles. Users can purchase rooms and furniture in Zwinktopia with Zbucks, in-game cash that can be earned by exploring areas, playing games, or inviting friends to create their own Zwinky avatars. Zbucks are also purchasable with a credit card or PayPal account.

IAC has yet to announce a launch date for Green.com or any details for a monetization plan similar to Zwinktopia's Zbucks system. The forthcoming community will replace the coupon offerings currently hosted at the site.
