Fighting for the same sweet
Despite a whopping 117 percent year-over-year growth in unique audience, which numbered 19.2 million in August, Facebook remained behind MySpace, which is entrenched at the top of the US Social-Networking hierarchy with 60.3 million unique visitors, according to Nielsen/NetRatings, MarketingCharts reports.
NetRatings released data last week on August's top US social networking sites, blogs and video sites, ranked by unique audience.
MySpace's 23 percent growth in unique audience from August '06 to August '07 translates into an increase of more than 11 million unique visitors - or more than half of Facebook's unique audience.
In short, in terms of absolute numbers, both social-networking sites gained similar numbers of unique visitors over the previous year - albeit one (Facebook) from a much smaller base, therefore all the more impressive.

Video Sites
Yet another Google property, YouTube, led the list of top 10 video sites in August with 56.5 million unique visitors - up 66 percent from August '06. Google Video, with 14.5 million unique visitors was third.
The largest growth among the video sites came from Veoh, which increased its unique audience nearly 350 percent, to nearly 3 million.

Sandwiched between the Google sites was MySpace Video with 16.8 million unique visitors in August - down 6 percent from a year earlier.
Yahoo Video, meanwhile, soared 101 percent from a year earlier, and is challenging rival MSN Video for the fifth spot.
Blog Sites
Google's Blogger remained atop the top 10 list of blog/host sites with 31.3 million unique visitors in August - 58 percent more than a year earlier. It was followed by AOL's tmz.com, with 9.5 million.
The biggest surge in the blog category has been by WordPress, which had a unique audience of 8.9 million in August - or 322 percent more than a year earlier.
