GSMA Mobile Media Metrics Report Issued on UK Mobile Applications Usage

Google Owns 3 Out of 5 Top Ranked Apps

LONDON, UK, 22 June, 2011 – The GSMA and Comscore, Inc. (NASDAQ: SCOR), in partnership with the UK mobile operators, today released the first monthly data showing how UK mobile consumers engage through mobile applications. The data from the GSMA Mobile Media Metrics (MMM) application key measurements report reveals that nearly 8.8 million UK mobile owners used an app that connected to the internet during April 2011, with Google Maps ranking as the most accessed app with 6.4 million unique users.

The application key measurement report includes hundreds of app titles and provides a ranking of the most popular connected applications in the UK. The application ranking is available as part of the GSMA MMM product portfolio, launched in February last year, which includes monthly reports on mobile internet behaviour and a detailed analysis of access methods.

“We are excited to release the first public census-level data from the GSMA and Comscore on mobile application usage,” said Henry Stevens, Media Director, GSMA. “Apps have become an important entry point for accessing content on mobile devices and their usage will only increase with the rapid proliferation of smartphones. We look forward to delivering to the UK market these critical insights to help understand the mobile ecosystem.”

Jeremy Copp, VP Mobile for Comscore Europe added, “To help better measure publishers’ mobile assets, we offer mobile-optimised tagging to publishers free of charge. This service gives clients the ability to tag mobile-optimised websites and applications to enable accurate measurement of audiences, including unique visitor counts and engagement metrics, across a variety of devices and platforms. By tagging mobile applications, we can expand the ranking of applications currently under measurement and media owners as well as publishers can be sure that their properties are correctly represented in the metrics and audience measurement rankings.”
