Smartphones aggressively saturated the mobile market in 2010, driving an increase in mobile media consumption by users worldwide, according to a new report from comScore.

“2010 was a game-changing year for the mobile industry,” said Mark Donovan, comScore senior vice president of mobile. “Smartphone adoption, 3G penetration and unlimited data plans drove a surge of mobile media consumption across geographies and deepened the integration of mobile devices into everyday life.”

“And, the coming year has the potential to be even more exciting. As the mobile ecosystem continues to develop, including progress in mobile advertising and commerce, it’s clear that mobile is destined to become an increasingly important platform for digital marketers across all industries.”

Smartphone adoption increased in both the U.S. and Europe. U.S. smartphone adoption reached 27 percent of mobile subscribers in December 2010, an increase of 10 percentage points from the previous year, while European adoption reached 31 percent, also up nearly 10 points versus year ago.

Nokia was the top handset maker in the UK, Germany, Italy and Spain. Samsung took the top spot in the U.S. and France, and also ranked in the top three in the UK, Germany, Italy and Spain.
