YouTube alone claims &amp;quot;100 hours of video are uploaded to YouTube every minute&amp;quot;:&lt;p&gt;&lt;a href=&quot;https://www.youtube.com/yt/press/statistics.html&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;yt&amp;#x2F;press&amp;#x2F;statistics.html&lt;/a&gt;&lt;p&gt;...which comes out to 144kh&amp;#x2F;day. In other words, one of these discs would be enough to store ~3 days worth of contributions to YouTube. So a box of these discs, let&amp;#x27;s say 1000 of them - which isn&amp;#x27;t all that big (e.g.  &lt;a href=&quot;http://www.amazon.co.uk/Neo-Aluminium-Storage-1000-sleeves/dp/B0010IIJ9U&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.amazon.co.uk&amp;#x2F;Neo-Aluminium-Storage-1000-sleeves&amp;#x2F;d...&lt;/a&gt; ), could hold an archive of every single video that has ever been uploaded to YouTube.&lt;p&gt;I am now reminded of this: &lt;a href=&quot;http://www.youtube.com/watch?v=Y_UmWdcTrrc&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=Y_UmWdcTrrc&lt;/a&gt;&lt;p&gt;Edit: got beaten to mentioning YouTube, but there&amp;#x27;s many other video sharing sites on the Internet, and of course there are probably countless hours of one of the types of video the Internet is well known for: porn.</text></comment>

Lower quality, and probably with (near) duplicates, but I guess it is safe to say we have that amount of video.&lt;p&gt;Another way to look at it: I expect we produce more content in unique wedding videos every year (at an hour each, that takes half a million weddings or a million people marrying. At an average of one marriage per life and a life expectancy of 75 year, that takes a population of 75 million people)</text></comment>
