In Europe, Apple iOS Ecosystem Twice the Size of Android When Accounting for Mobile Phones, Tablets and Other Connected Media Devices

comScore Releases First European Data on Media Tablet Users from MobiLens Service

LONDON, April 21, 2011 - comScore, Inc. (Nasdaq: SCOR), a leader in measuring the digital world,
today released the results of an EU5 (UK, Germany, France, Spain, and Italy)
study of media tablet owners, based on data from the comScore MobiLens
service. The report includes comScore's first publicly available data showing
demographics and other characteristics of users of connected media devices,
such as the iPad, iPod Touch and devices running on Google's Android
software. Initial research indicates that Apple's iOS platform, which resides
on iPhones, iPads and iPod Touches, has a combined platform reach of 28.9
million users in the five European markets, outreaching the Android platform
by 116 percent.

"comScore is excited to offer insights about the comprehensive mobile
ecosystem, including connected media devices, such as the iPad," said Jeremy
Copp, comScore vice president of mobile in Europe. "This new data set is part
of our MobiLens service and enables our clients to understand the detailed
demographic and behavioural attributes of connected media device users. This
of course has significant implications for the media and developer
communities as they consider how best to reach their audience on all types of
connected devices."

Devices Running on Apple iOS Used by Nearly 29 Million in EU5

comScore's analysis of the unduplicated audience reach of the Apple iOS
platform across iPads, iPhones and iPod Touches revealed a combined iOS
installed base of 28.9 million users across the five markets analyzed (UK,
Germany, France, Spain, and Italy). With 16.1 million users across these five
markets, the installed base of iPhones by far exceeded that of iPod Touches
and iPads. The combined 28.9 million iOS users is 116 percent greater than
the 13.4 million combined Android OS installed base, which includes users of
both phones and connected media devices running on Google's operating system,
such as the Samsung Galaxy Tab.

Apple iPad Ownership Extends Beyond Apple Loyalists

The research in Europe also suggests that iPad ownership extends well
beyond Apple's most loyal consumers. Although a perception may exist that
iPad owners tend to be those with a very strong affinity for Apple products,
an analysis of the mobile devices of iPad owners indicates that may not be
the case. Though iPhone users are well represented among iPad owners in
Europe, a substantial percentage of this group uses other phones as their
primary mobile devices.

Apple ranks as the most heavily represented OEM among iPad owners, with
its OEM share of 27.2 percent particularly higher than its share among all
smartphone subscribers (20.6 percent). Nokia mobile phone users account for
the second highest percentage of iPad owners at 26.4 percent, but this number
is well below its overall smartphone market share of 41.7 percent. Meanwhile,
LG, Motorola, Samsung, and Sony Ericsson are all overrepresented among iPad
owners as compared to their respective shares of the smartphone market. In
addition, 5.9 percent of iPad users had Android phones across the five
European markets.

"This data clearly illustrates that the Apple ecosystem extends far
beyond the iPhone, but it also shows that there is significant penetration of
iPad users amongst owners of other handset manufacturer's devices," added
Copp. "Blackberry users are the only segment of users to buck this trend and
are significantly underrepresented among iPad owners, which is perhaps a
signal of brand loyalty as they awaited the launch of the Blackberry
Playbook."

Apple iPad Ownership Skews to 25-34 Year Old Males

Across the five European markets analyzed more than 62 percent of iPad
owners were male, skewing well above the average gender split for mobile
owners. The age profile of European iPad users indicated the heaviest skew
toward 25-34 year olds (23.4 percent) in relation to the total mobile
audience (17.3 percent). iPads also exhibited an above average skew in the
18-24 year old age segment. However, this demographic profile was similar to
that of the smartphone user base, indicating that the advanced mobile
capabilities rather than the device itself might be primary driver behind
this age profile.
