Mobile browsing has more than doubled in the last year and now accounts for over 6 percent of all online activity, a Web statistics company said last week.

And Apple's Safari -- the default browser on the iPhone, iPad and iPod Touch -- rules the usage share roost, representing 53 percent of the mobile browsing market.

Two trends are clear, said Vince Vizzaccaro, a vice president with metrics firm Net Applications, which released new figures. "Phones and tablets are stealing [browsing] share from desktops at an accelerated pace," said Vizzaccaro.

Net Applications calculates browser usage share with data obtained from more than 160 million unique visitors who browse 40,000 Web sites that the company monitors for clients.
