European Smartphone Market Grows 41 Percent in Past Year

Nokia Continues to Lead Smartphone Market But Apple and Android Devices are Gaining Fast

LONDON, September 14, 2010 - comScore, Inc. (Nasdaq: SCOR), a leader in measuring the digital world,
today released a study of smartphone use showing that the Symbian platform
holds 54.4 percent of the Western European market. Despite Symbian's
continued growth in number of smartphone subscribers, its market share has
fallen as growth in the Apple OS and Android (Google) platforms has surged in
the past year.

Smartphone adoption in the EU5 (U.K., France, Germany, Spain, Italy) has
grown 41 percent in the past year to 60.8 million subscribers. Currently,
more than one out of every two smartphones is a Nokia manufactured device,
although Nokia accounted for more than two out of every three smartphones a
year ago.

"Nokia is still the clear leader in the European smartphone market and as
the eagerly anticipated N8 launches, all eyes are on Nokia," says comScore
European VP Mobile, Jeremy Copp. "While Nokia has made great strides with
offerings such as the Ovi Store and Symbian 3, the pressure is on to reclaim
valuable market share. By innovating and bringing new phones to market for a
wide variety of audiences, Nokia's future is not predicated on the success of
one handset alone."
