comScore: Smartphones driving Twitter adoption in U.S.

Nearly 93 million users worldwide accessed microblogging platform Twitter in June 2010, a year-over-year increase of 109 percent, according to new data issued by research firm comScore (which adds its metrics do not account for usage via Twitter-based applications like TweetDeck). Latin America experienced the strongest regional growth, increasing 305 percent to 15.4 million users, followed by Asia Pacific, which climbed 243 percent to 25.1 million visitors. Indonesia boasts the highest Twitter penetration, with 20.8 percent of the nation's Internet users visiting the site in June--Brazil (20.5 percent of users) and Venezuela (19.0 percent) follow, with comScore crediting surging Venezuelan use to president Hugo Chavez joining Twitter in late April.

Close to 25 million North American users accessed Twitter in June. The service enjoys a higher maturity level in North America than in other global regions, posting year-over-year growth of 22 percent. comScore notes that 8.3 percent of U.S. smartphone users (about 4.2 million consumers in all) now access Twitter.com via mobile device each month, outpacing the U.K. (5.8 percent of smartphone users), Germany (3.1 percent) and France (2.1 percent).
