ClickZ: Big Results From PDA-Based Advertising

You might think everyone on the planet has a PDA, but alas, that isn't true. "Only" seven percent on U.S. households are predicted to have a PDA user by 2008, according to Jupiter. But PDA users are most often the cream of the demographic crop - highly educated, higher income and more Internet savvy.

Through aggregation services such as Vindigo and AvantGo, advertisers can reach this highly desirable segment through channel sponsorship or even through the creation of a content channel. One of ClickZ writer James Hering's automotive clients recently ran a campaign on AvantGo and saw costs per lead half that of comparable web-based campaigns. This is not surprising, given the uncluttered content environment of the PDA and the control the user has over the content that is delivered.
