YouTube users are now uploading more than 35 hours of video to the Google-owned video site every minute, the company announced Wednesday.

That equals 2,100 hours uploaded every hour, or 50,400 hours uploaded to YouTube every day. "Thirty-five hours a minute is the equivalent of over 176,000 full-length Hollywood releases every week," YouTube said in a blog post. "Another way to think about it is: if three of the major U.S. networks were broadcasting 24 hours a day, 7 days a week, 365 days a year for the last 60 years, they still wouldn't have broadcast as much content as is uploaded to YouTube every 30 days."

YouTube video uploads have actually doubled in the last two years, YouTube said. In May 2009, YouTube said its users uploaded 20 hours of video every minute; that number jumped to 24 hours by March 2010.

YouTube attributed its growth to several factors. In July the site increased the time limit by 50 percent from 10 to 15 minutes. Upload file size has also increased more than 10 times to its current 2GB. YouTube also pointed to phones that have "improved dramatically in how quickly and easily they upload videos to YouTube" as well as an increase in the number of companies integrating its API - "Call of Duty: Black Ops," users can record and share video footage.

As a result, YouTube is challenging its users to uploade 48 hours of video every minute; 100 percent growth over March 2010 levels.
