NEW YORK - Jupiter Media Metrix predicts that worldwide advertising, commerce, and subscription revenue from mobile phones will reach $7.5 billion by 2003 but that North American revenue would be $700 million - less than 10% of the total.

Asia will lead with about a 66% share, or $5 billion, of worldwide revenue, according to Jupiter analysts, and Western Europe will have $1.7 billion. Nearly all mobile content providers in the United States, they said, will have negative returns on investment in the short term because they lack direct revenue sources such as subscriptions or per-minute revenue sharing.

"Despite a growing wireless audience, the U.S. is a revenue wasteland for mobile phone content providers," said Jupiter analyst Dylan Brooks. "Mobile content providers must think in terms of long-term investment rather than short-term return on investment, as mobile revenue will remain extremely limited for the foreseeable future."
