Opera is celebrating after hitting the 100 million mark in global users of its browsers. Half of the audience’re using mobile version of Opera’s Browser, Opera Mini. As of March 2010, 50 million unique active users were browsing on Opera’s desktop offering on Windows, Mac and Linux computers and 50 million people were using Opera’s mobile browser. Opera has been boosted by Windows ballot screen, which was brought in by Windows following the company’s high-profile complains to European Commission. And with a 50/50 split between PC users and people who use Opera on mobile devices, company is celebrating a 30% year-on-year growth for its flagship desktop browser, according to March figures. “Opera for Desktop delivers the fastest browsing experience on the planet, with a visionary approach to features and a user-friendly design.” Opera’s total percentage of the global browser market remains small, although its place in the top five browsers means that it gets a prized place on the first ballot screen from Microsoft.
