“This report represents an important benchmark in the evolution of mobile Internet audience measurement,” said Herve Le Jouan, Managing Director, comScore Europe. “But beyond this – we are now at a pivotal stage in the development of the entire online industry, and if any U.K. marketers were still awaiting a sign that the mobile Internet platform has come of age, then the launch of the iPhone 3G certainly provided it. We hope that this research will provide valuable insight for the industry as a whole and promote further understanding of mobile Internet audience behavior as we move into an increasingly converging online world.”
