YouTube pushed ahead of MSN/Windows Live in May to become the fourth-ranked Web property, with 127.5 million unique monthly visitors, according to the latest Nielsen data. That gives Google, which again had the largest online audience last month, at 173 million, two of the four top sites. Sandwiched in between were Facebook (152 million) and Yahoo (143 million).
While Facebook’s traffic held about steady from April, time spent on the site slipped slightly from seven hours, nine minutes to 6:53 in May. Among the top 10 sites, Yahoo was next closest in time spent, at 2:31.
For its May report, Nielsen also spotlighted the top news brands online. Yahoo-ABC News sites was the leader, with an audience of 62 million, followed by CNN (39.6 million), HPMG News sites (formerly AOL News), at 33.5 million, MSNBC (30.2 million) and NYTimes.com (29.2 million). Among the top 10 news sites, people spent the most time at CNN, at 35 minutes on average, and logged the most page views, at 42 each.
Overall, 212 Americans were online in May, spending 29 hours on average browsing the Web.
