Internetional Hearald Tribune:
The mobile phone, the pitch goes, could be the most powerful marketing tool ever invented. Until recently, however, cellphones have been mostly about talking the talk (or texting the text). Now, from an advertising perspective, there are signs that they may be starting to walk the walk.
Worldwide, there are twice as many cellphones as PCs, and in developed countries, at least, most new phones can provide access to the mobile Internet. For advertisers who want to know more and more about their audiences and how they spend their days, cellphones can even one-up the old-fashioned, wired Internet: Not only can they track users’ online clicks, they can trace their steps, too, making it possible to home in ever more closely on target audiences.
Despite the obvious potential, however, advertising via cellphones has been slow to develop, except in Japan and South Korea. One reason is the sluggish take-up of content services delivered via high-speed wireless networks. Also, analysts say, cellular operators have been reluctant to yield the equivalent of television or Web-site ratings for their mobile media offerings, frustrating marketers who crave “measurability” when buying advertising space and time.
SMS-based campaigns inviting consumers to request product information or to register for contests via text messages have proved effective in reaching niche audiences in Europe. Because of a fear of spam, however, regulators and mobile operators have required advertisers to limit this to customers who “opt in.”
