AdMob: iPod touch use jumped in January

Mobile advertisement firm AdMob has revealed its Mobile Metrics report for January. According to the data, worldwide requests from Apple devices grew 28% month over month to 1.2 billion in January, with the iPod touch outpacing the iPhone’s growth in top markets. The iPod touch now represents 40% of ad requests from Apple devices, doubling September’s 20% share. In early January, AdMob revealed that iPod touch requests had more than tripled worldwide from November to December; it is unclear how many of these increases can be attributed to sales of AdMob-supported applications.
