Juno Online Services, Inc. (NASDAQ:JWEB) today announced the launch of a co-branded version of AOL Instant Messenger(SM) (AIM) for Juno users.

The new co-branded Juno Instant Messenger enables Juno subscribers to chat in real time with other Juno members, AOL members, AIM members, and other Internet users.

Juno intends to promote instant messaging to its membership over the next several months through prominent links on its Web site and in the bimonthly e-mail newsletter it distributes to its subscribers. In addition, Juno will mount a marketing campaign over the Juno service that will use banner, pop-up, and interstitial advertisements to tell its millions of subscribers about the new service.

&uot;We're absolutely delighted to offer this co-branded instant messaging application in the suite of branded communication services we offer our members,&uot; said Toby Bryce, the vice president at Juno responsible for the relationship with AOL. &uot;We've worked with AOL to ensure that Juno Instant Messenger is as intuitive and easy to use as people have come to expect from a Juno service. Instant messaging is an important component in the multimedia communications environment we provide for our users, and we believe that it may become one of our most popular services.&uot;
