Google recently confirmed that YouTube now receives more than 4 billion video views per day. Reuters reported the news Monday morning and noted that the site has seen a 25% increase in videos viewed per day since May. Google, which owns YouTube, also confirmed that there are more than 60 hours of fresh video uploaded each minute, up from the 48 hours of video added per minute in May. Advertisements on videos generate roughly $5 billion in revenue each year, Reuters said, but just 3 billion videos feature ads each week. The growth in viewership was attributed to users accessing the service from smartphones and televisions.
