Turner Broadcasting announced Wednesday that it will launch a new UK Web site for its Cartoon Network children's channel, June 16th, that will heavily feature interactivity, community and personalization. Among other things, Turner says, the site will offer a social-networking service, called "My CN," that will allow children to interact "safely" with one another, using a range of pre-selected statements and messages. Visitors to the site will also be able to customize its look, using it a selection of backgrounds; choose avatars based on various Cartoon Network characters; chat with their friends; and play games to win virtual prizes.
