The Web Motivation Inventory (WMI) is used in internet advertising research, and is frequently used and cited in advertising, marketing and communication literature. Investigations of the robustness of the WMI have been somewhat limited. Additionally, new uses of the internet are not accounted for by the WMI since its publication in 2002. This paper replicates and extends the original WMI using participants in the US, UK and Australia and includes internet motives not previously examined. The results show that the four-factor WMI remained reliable and valid for all three samples. Findings suggest the extended WMI may be broken into 12 sub-scales that represent the original fourfactor measure.
IntroductionInternet advertisers in the US spent $7.9 billion during the first six months of 2006 -a 37% increase over the first half of 2005 (IAB 2006). Increase in online advertising reaffirms the internet's growing importance for advertisers and marketers who want to engage consumers and leverage branding opportunities. From search engines, behavioural targeting, consumer-generated content, broadband and new emerging platforms such as mobile and iPTV, the internet is projected to continue to increase its share of total ad spending (IAB 2006).
