YouTube has experienced an incredible growth over the past year, according to the news agency Reuters. Every day a staggering 4 billion videos is streamed by users of the service, which is a growth of 25 percent compared to eight months ago. Every minute an average of 60 hours of video is uploaded to the service, compared with 48 hours in May last year.

The growth is explained by the fact that the video service is made ​​available on an increasing number of platforms. Previously, Youtube videos was mainly streamed via the computer screen, but the past year, smart phones and TV applications has made YouTube available almost everywhere.

YouTube was acquired by Google for $1.65 billion in 2006, and has become one of its biggest sources to generate revenue outside its traditional advertising business.

Last week, Google said that its business running graphical “display” ads – many of which are integrated alongside YouTube videos – was generating $5 billion in revenue on an annualized run rate basis.

Still, most of the 4 billion videos that YouTube now streams worldwide every day do not make money. Three billion YouTube videos a week are monetized, according to the company.
