Related to my post the other day on print's perfect storm is a report from Nielsen that the US is among those leading in the adoption of mobile Internet penetration.

Key takeaways from from the report include:

  • The US, UK and Italy are leaders in mobile Internet penetration. 15.6 percent of mobile subscribers in the US, 12.9 percent of subscribers in the UK and 11.9 percent in Italy actively use the mobile Internet

  • We believe mobile Internet has reached a critical mass as an advertising medium in the US. As of May 2008, there were 40 million active users of the mobile Internet in the US, with individual sites that attract millions of unique users. This provides scalable marketing potential with demographic breadth.

  • As mobile Internet publishers build out an advertising inventory, advertising is becoming a common part of the mobile Internet experience: 26 percent of mobile Internet users recall seeing some form of advertising while using the mobile Internet. Mobile Internet users are 60% more likely to be open to mobile advertising than the average mobile data user.
