Where did you spend your time online in May? Nielsen knows

Did you know that you probably spent more than a full day online in May? And you were probably spending a good portion of that time somewhere on Google, checking out a news site or watching hours and hours of YouTube videos.

On average, the nearly 212 million Americans online last month spent about 29 hours browsing the Web, according to Nielsen. An average of just under six hours of that time was spent watching videos -- more than 26 billion videos. The brand with the biggest draw was Google, pulling in 173 million unique visitors. That was nearly 20 million more than the next site -- Facebook, with 152 million. That said, users spent more time on Facebook (on average, nearly seven hours last month) than on Google (1 hour, 40 minutes), according to Nielsen.
