Mobile commerce to remain a niche in the U.S.

According to InfoWorld, a study released this week by Jupiter Media Metrix shows tha the US has the largest base of cell phone users in the world, but Internet-capable wireless phones will account for less than 2 percent of American online shopping by 2006. Less than $4 billion in shopping and travel will be conducted on Internet-capable mobile phones in the United States by that time. But shopping-related content on mobile devices will influence transactions online via PCs and off-line at traditional brick-and-mortar stores -- sales that will be valued at $39 billion in 2006, Jupiter analysts predict. "The key recommendation is that real commerce opportunity here isn't so much for companies online," but for companies such as WalMart and Kmart to alert customers of what they may want to buy in the stores, said Joe Laszlo, wireless analyst at Jupiter.
