Mobile Social Networking Audience Grew 44 Percent Over Past Year in EU5

Twitter and LinkedIn Mobile Audiences Doubled in Past Year

LONDON, UK, 21 November 2011 - Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released an overview of mobile social media usage across the five leading European markets (France, Germany, Italy, Spain and the United Kingdom) from the Comscore MobiLens service. The study showed that the audience for mobile social networking in the EU5 region grew 44 percent in the last year with 55.1 million mobile users in the EU5 accessing social networking sites or blogs via their mobile devices during September 2011.

“Over the past year we have seen social networking use grow rapidly among mobile users across Europe, driven largely by the growth in smartphone adoption, making it easier than ever for users to stay connected and engage in social activities while on-the-go,” said Jeremy Copp, Comscore Europe vice president for Mobile. “More notably, the rate of growth in daily social networking usage has surpassed even the rate of growth in total social networking adoption among mobile users, suggesting that the behavior is becoming even more ingrained into people’s daily mobile lives. As social networks continue to invest in improving the user experience on mobile devices and tablets, it will be interesting to see how social behaviours on the mobile platform further evolve.”

1 in 4 EU5 Mobile Users Access Social Media
In September 2011, 55.1 million EU5 mobile users accessed social networking sites or blogs on their mobile device, representing 23.5 percent of the total mobile audience. Nearly half – 46.8 percent – of this audience reported accessing social networking sites on a daily basis. Interestingly, the growth in daily social networking use from the previous year outpaced that of mobile social networking access as a whole (67 percent vs. 44 percent), indicating that the mobile platform is proving to be conducive to very frequent social networking use. While most mobile users accessed social networking sites via a mobile browser (31.3 million), the number of people using mobile apps doubled in the previous year to 24.2 million.

Twitter and LinkedIn Mobile Usage More than Doubles Over the Past Year
Several social networking brands posted significant gains for their mobile audiences over the past year. Approximately 39 million mobile users or 71 percent of the EU5 mobile social networking audience accessed Facebook via a mobile device in September 2011 – the largest mobile audience of any social network – and an increase of 54 percent in the past year. Nearly 8.6 million mobile users accessed Twitter.com, representing a 115-percent jump from the previous year. LinkedIn grew by a notable 134 percent to 2.2 million unique users, more than doubling its user base during the same time period. Spanish social network Tuenti.com received 2.3 million unique users, growing nearly 60 percent.
