U.S. Mobile Social Media Audience Up 37 Percent in 2011
By Anna Johnson on October 24th, 2011U.S. mobile social media usage rose by 37 percent in the past year, with 72.2 million Americans accessing social networking sites or blogs via mobile device in August 2011, according to research by comScore, Inc.
Almost 40 million U.S. mobile users – over half of the estimated U.S. mobile social media audience – visit social media sites via mobile each day, reports the research firm.
comScore’s research also shows that, right now, more mobile users access social media sites via their mobile web browser than via a social networking app (42.3 million compared with 38.5 million).
This is likely to change, however. The growth in users accessing social media sites via social networking app is much higher than the growth in access via mobile browser. In the last year those accessing social media sites via mobile browser rose by 24 percent, compared with the huge 126 percent growth in the audience for social networking apps.
