Americans viewed some 11 billion videos during July, and they watched most of them on Google sites, according to the latest metrics from comScore. Of the more than 11.4 billion videos viewed in the month, nearly 44 percent were seen on Google (GOOG) properties. And 98 percent of those were viewed on YouTube, which continues to dominate the online video space. The remaining 55.9 percent was split among nine properties led by Fox Interactive Media and MySpace (NWS), which ranked a very distant second to Google, with just 3.9 percent of videos viewed. None of the remaining eight sites even cracked three percent.

So who’s watching all this video?

Answer: nearly 142 million U.S. Internet users–almost 75 percent of Americans with Internet access. On average they spent 235 minutes watching video in July. And they rarely spent more than 2.9 minutes on any one video, which makes perfect sense when you think about it. “Dramatic Chipmunk” is just five seconds long, and I’m told it’s the greatest video on the Internet.

But not to worry, MySpace has a solution for that. It’s just one that lacks an obvious monetization strategy. It’s called Data Availability and it’s a way for MySpace members to share and sync profile data across partner sites–starting with Yahoo (YHOO), eBay (EBAY), Twitter and Photobucket. “The walls around the garden are coming down–the implementation of Data Availability injects a new layer of social activity and creates a more dynamic Internet,” enthused Chris DeWolfe, CEO and co-founder of MySpace, in a statement. “We, alongside our Data Availability launch partners, are pioneering a new way for the global community to integrate their social experiences Web-wide.”

That’s all well and good. But how about pioneering a new way to, you know, make money off that integration? Data portability is wonderfull and all. But so is revenue. And right now, MySpace’s Data Availability initiative doesn’t include any advertising deals.
