Internet Explorer falls below 50 percent global marketshare, Chrome usage triples

ブラウザシェアはさまざまなリサーチ会社が定期的に発表していますが、StatCounterが今年9月分でまとめた調査結果には一つ大きなニュースがありました。それはマイクロソフト Internet Explorerのシェア50%割れ。世界シェアは49.87%となり、同社の調査で過去最低となっています。二位に続くのはFirefox(31.5%)ですが、IEのシェア低下ぶんを拾いあげたのはむしろ三位に位置するGoogle Chrome(11.54%)。去年9月時点では3.69%しかシェアがなかったことを考えるとまさに急伸です。StatCounterのCEO Aodhan Cullenは「ブラウザ戦争における確かな節目だ」「たった2年前、IEはシェア67%で世界の市場を独占していた」とコメントしています。

Firefoxを支援していたGoogleが独自ブラウザを発表したときは驚きをもって迎えられましたが、いま思えばAndroidGoogle TV、そしてChrome OSとプラットフォーム戦略を進める上での第一歩だったと言えます。IEは9、Firefoxは4と、それぞれ登場を待つ次期バージョンで猛追に対抗するかまえ。HTML5+CSS3の世界ではウェブブラウザの役割がさらに増すことを考えると、一度は終結したかに思えたブラウザ戦争も実際はまだこれからなのかもしれません。

Microsoft's Internet Explorer Browser Falls Below 50% of Worldwide Market for First Time – StatCounter

BOSTON & DUBLIN--(BUSINESS WIRE)--Microsoft's Internet Explorer (IE) browser has fallen below 50% of the worldwide market for the first time according to StatCounter. The company's research arm, StatCounter Global Stats finds that Microsoft IE fell to 49.87% in September followed by Firefox with 31.5%. Google's Chrome continues to increase market share at an impressive rate and has more than tripled from 3.69% in September 2009 to 11.54% in September this year.

"This is certainly a milestone in the Internet browser wars"
"This is certainly a milestone in the Internet browser wars," commented Aodhan Cullen, CEO, StatCounter. "Just two years ago IE dominated the worldwide market with 67%."

He added that Microsoft's agreement with European Commission competition authorities to offer EU users a choice and menu of browsers from March may have tipped IE below 50% globally.

In Europe, IE market share has fallen to 40.26% in September this year from 46.44% in September last year. In North America IE is still above 50% at 52.3% followed by Firefox at 27.21% and Chrome at 9.87%.

The rise of Google Chrome in North America has also been impressive and in June it overtook Safari for the first time.
