Blyk, the free, ad-supported mobile network for the under-25 crowd, has hooked up with mobile marketing and content services provider Velti to launch a new content portal. Dubbed On Blyk, the messaging-based portal lets companies offering contents and services determine their own pricing and promotions.

Where most content services are based on browsing for content, On Blyk is testing the theory that since messaging is the dominant mobile activity for Blyk's target audience, that its subscribers will turn to messaging for their content discovery as well.

Companies such as Player X, Saffron Digital, Jumbuck and others have signed on to offer video, chat, wallpapers, games and ringtones on On Blyk.

The portal is currently open to all Blyk users in the UK.
