十年来浏览器行业没有出现新内核

Opera首席执行官Jon S. von Tetzchner今天表示,就浏览器来说,虽然互联网经历了十年的高速发展期,但浏览器内核本身实际没有实质突破,谷歌Chrome虽然是个新的浏览器,但与苹果Safari一样都是基于WebKit内核,"可以说,十年来浏览器本身没有出现新内核",Jon表示。 作为一家老牌的浏览器厂商,Opera浏览器桌面版市场占有率远远落后于IE和Firefox,但是在移动产品市场中,Opera却处于遥遥领先的地位。IDC今年10月的统计数据显示,Opera mini版全球活跃用户已经超过2100万,同时Opera还通过与老牌游戏机厂商任天堂合作将Opera 浏览器内置到NDSL掌机和热销的Wii游戏机中,Jon表示,"Opera mini 是我们目前最重要的产品之一,今年1到9月Opera mini的用户量增长超过350%,在中国我们也通过与空中网的合作不断提升市场份额"。Opera mini也使用了云计算的概念,在手机上网时,服务器端会进行数据压缩,手机用户上网访问WWW网页会拥有更快的速度和效率。 事实上,Opera是目前全球唯一一家跨平台浏览器厂商,Jon表示,"不管是手机、还是移动设备、还是机顶盒、还是电脑,Opera都可以提供优质快速稳定的浏览器。" 不过Jon也坦陈,"对Oprea来说,我们的营收主要来自三个方面,比较传统的仍然是软件授权预装和桌面版流量点击分成,不过从今年开始,Opera已经开始与T-Mobile等重要运营商开始按照Opera mini的用户活跃度进行合作分成,这是Opera未来的一个巨大增长点。" 1995年末,Jon S. von Tetzchner与Opera总程序设计师Geir Ivars y在挪威成立Opera Software 公司,之前两人供职于挪威最大的运营Televerket ,1995年,Televerket 更名为今天的Telenor。   2008-11-28   洛阳生活信息点评网:http://luo...
