YouTube has passed yet another milestone: it now serves more than 4 billion daily video impressions to its adoring audience. That's the report from Reuters, which cites information direct from Google that also notes roughly 60 hours of new content are being uploaded to YouTube every minute. That's a 25 percent increase from the 48 hours users were uploading back in May, when the video hosting website was dolling out only 3 billion video views per day.

The growth of YouTube can be attributed to a number of factors, including the popularity of Android in the mobile space and a recent redesign of the web client. Still, it's not a foregone conclusion that the insatiable appetite for web video would all go Google's way — there are plenty of competing streaming services now — so the company must be doing something right to not only retain but expand its massive following.

Update: Google has now taken to its YouTube Blog to also brag about the numbers, illustrating them with the video below.
