Microsoft tops Google, Yahoo, Facebook in worldwide Web use

Windows Live Messenger led Microsoft's Web properties in capturing 14.5 percent of total time spent online in September worldwide, handily beating Google, Yahoo, Facebook and other sites, according to analysis firm comScore.

In fact, people spent 36 percent more time on Microsoft sites than they did on sites owned by second-place Google, and 57 percent more time than on Yahoo sites. That's out of an estimated 27 billion hours spent online globally in September (excluding public computers and smartphones), comScore said.

Windows Live Messenger accounted for nearly 70 percent of the 3.9 billion hours people spent on Microsoft Web properties, the firm said.

People spent 2.5 billion hours on Google sites, 1.2 billion hours of which were spent on YouTube. Facebook was the fastest-growing property, its share of attention jumping 193 percent over September 2008, according to comScore.
