U.S. social media usage on mobile devices is up, way up, according to a new study by ComScore. The study determined that social networking is the fastest growing activity by people using web enabled mobile devices, for both application and browser access.

Out of the 69.6 million people who used mobile apps for the 3 month period ending in April, 14.5 million accessed social networks. This is a 240% increase from the previous year.
In addition, out of the 73 million people who used mobile browsers, 30 million used social networks through a browser. This is a 90% increase from the previous year.
When combined with the finding early this year, that mobile web usage grew by 110% in the U.S. last year and 148% worldwide, it’s obvious that mobile social networking is going to continue to experience strong growth for the foreseeable future, and not just in the U.S. The development of mobile tablet devices such as iPads is certainly going to contribute to the trend too.
How often do you access social networks via mobile rather than fixed line these days? With me, I’d say it would be about 20-30%, perhaps more. It’s certainly increased since I started using location-based services such as Foursquare.
