Google's rise in the browser market is in part down to nationwide advertising – Chrome is the first Google product advertised on British TV – but is largely attributed to its speed.
Unlike most of Google's talent based at its Mountain View headquarters in California, Bak works from a converted farmhouse in the Danish countryside two hours from Copenhagen. He has become obsessed with speed, and despite numerous tests that show Chrome outstrips all rivals, he thinks it could be much faster. "You should never be happy with [existing] speed," he said. "Of course it gets harder to make substantial gains, but it's all healthy competition. From the beginning we wanted everybody to be fast, and now all browsers are fast. I'm absolutely flabbergasted [by the improvements made by rival browsers]."
Chrome is the number three worldwide, with a 20.65% market share according to Statcounter. But analysts expect it to edge ahead of Firefox, which has dipped steadily since January. Microsoft's Internet Explorer has also fallen heavily, to 43%, with warnings about security vulnerabilities.
Google last month announced its Chromebook laptop, based on its browser and seen as another ambitious attack on Microsoft; it will be made by Samsung and Acer, companies that previously made computers running Microsoft's software.
Unlike most computers, the Chromebook has almost no capacity to store and hosts most data online in a "cloud". Bak said: "The Chromebook is really important because it tries to simplify the machine – it is basically no maintenance, which means you can cut the price. If all you are doing is using a browser it's a fantastic tool."
