"Social media is one of the most popular and fastest growing mobile activities, reaching nearly one third of all U.S. mobile users," said Mark Donovan, comScore senior vice president for mobile.

More than Half of Mobile Social Networkers Access Sites on a Near Daily Basis

In August 2011, more than 72.2 million people accessed social networking sites or blogs on their mobile device, an increase of 37 percent from the previous year. Nearly 40 million U.S. mobile users, more than half of the mobile social media audience, access these sites almost every day, demonstrating the importance of this activity to people's daily routines.

Research also indicated that although more people accessed these sites via their mobile browser, the social networking app audience grew five times faster in the past year. While the mobile browsing social networking audience grew 24 percent to 42.3 million users in the past year, the mobile social networking app audience surged 126 percent to 38.5 million.

Facebook Mobile Audience Approaches 60 Million Users

A look at selected social networking brands, Facebook, Twitter and LinkedIn, revealed that each grew their mobile audiences by at least 50 percent in the past year. Facebook was home to the largest mobile audience among the three destinations with more than 57 million mobile users in August, up 50 percent from the previous year. Twitter saw its mobile audience jump 75 percent to 13.4 million people, while LinkedIn's mobile audience climbed 69 percent to 5.5 million users.

70 Percent of Mobile Social Networkers Posted a Status Update While on Their Mobile Device

Understanding how mobile users interact with social media is important for brands looking to engage with on-the-go consumers. comScore recently released new social media metrics through its MobiLens service, offering deeper insights into mobile consumers' social media activities. Of those accessing social networking sites or blogs on their mobile device in August 2011, 80.3 percent read posts from people known personally, while 69.5 percent posted status updates while on their mobile device.
