ESPN, CBS Interactive properties GameSpot and, Manga Entertainment and MUZU.TV are the latest companies to advertise 15- and 30-second spots on Xbox Live.

Microsoft launched the advertising platform for Xbox 360 TV applications in December.

“With the growth of Xbox Live, advertisers no longer have to choose between digital and TV advertising — we’re offering the impact of TV and the interactivity and addressability of digital in one platform,” said Ross Honey, GM of Xbox Live entertainment and advertising at Microsoft. “As more and more industry leaders like ESPN work with us to help monetize their content on Xbox Live, TV media buyers win with the ability to extend their standard TV spots to this highly engaged consumer audience.”
