How big is MySpace? ESPN big. MTV big. New Mobile Service lauches with tie-in to social network.

MySpace is so big now--today at over 75.4 million users--there is a new mobile service that just launched with MySpace connectivity as its focus. Helio, a joint-venture of South Korean communications company, SK Telecom, and U.S. based ISP, EarthLink, may spark a new, service-oriented definition of the Web 2.0 term, "mashup".

MySpace now joins the ranks of Disney, MTV, ESPN, and CBS, major media brands who have chosen the Web or mobile networks as a means of breaking out of their traditional mediums, to reach more tech savvy consumers. MySpace is now just the latest that has launched its own "virtual mobile network" using leased network spectrum for voice and data services. For months now, MySpace has suprpassed MTV as the premier taste-maker for 16-34 year-olds. With many mobile phone users not actually using many of the advanced data features of their newer handsets, these major brands are hoping to reverse this trend by targeting new services at young, affluent users who are already active in consumer affinity groups and social networks.
