LG and Samsung are the top mobile-phone brands in the U.S. for advanced entertainment features, leading competitors Motorola and Nokia in adoption of phones with support for mobile TV, music, and games, according to Mobile Entertainment Platforms and Services (Second Edition), a new consumer study from Parks Associates.

Among owners of LG and Samsung phones, 12% and 11% reported having mobile TV features, respectively, compared with 8% of Motorola owners and 0% for Nokia owners.

"South Korea leads the world in adoption of mobile entertainment features and services," said Yuanzhe (Michael) Cai, director of broadband and gaming, Parks Associates. "Korean phone manufacturers have been able to take that experience and translate it into success in the American market, balancing good designs and advanced feature sets with reasonable costs."

Among the four leading brands, Motorola ranks third overall, and Nokia lags significantly in advanced entertainment features. Only 6% of Nokia phones support purchase of music tracks, compared with 22% and 20% of LG and Samsung phones, respectively.

"Nokia needs to introduce more advanced phone models if it is to succeed in the high-end and midrange markets," Cai said. "The challenge is even more acute now that the Apple iPhone is stirring up competition in the premium handset market."
