Mobile Web usage is still a nascent activity, but comScore put out some data on the information-consumption habits of consumers in the U.S. The number of people who access news and information daily on their mobile phones doubled from 10.8 million in January, 2008 to 22.4 million in January, 2009.
The second most popular mobile activity was social networking, with 9.3 million daily mobile users (although for some reason this number also includes blog access). While social networking is only half as popular as reading news, it is growing four times as fast, up from 1.8 million users a year ago.
An estimated 63 million people accessed news and information on their mobile phones at least once during the month. Of those, about a third did so via a downloaded application rather than a mobile browser, with the most popular downloaded app being maps. SMS-based search proved even more popular (with 14.1 million monthly users versus 8.2 million for downloaded maps.
