Comscore - US Mobile Internet use doubles year-to-year

Research firm comScore revealed that day-to-day Internet use on cellphones in the US has roughly doubled in the past year. Where about 10.8 million users are known to have visited the mobile web at least once a day in January 2008, about 22.4 million were doing the same at the start of 2009. Large jumps also occurred for once-a-week visitors, who surged from 10.3 million people to 19.2 million, while those who accessed the Internet at least once a month climbed from 36.9 million to 63.1 million.

Most of these were accessing news or other basic information, though comScore notes that there were major increases in the uses of more specific information. Social networking in particular exploded and saw use grow about 427 percent to where 9.3 million users regularly check sites like Facebook or Twitter. Other but less dramatic jumps have taken place for those checking financial information on their phones, checking movie showtimes, looking up businesses or checking entertainment news.
