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><parent_chain><item><author>Someone1234</author><text>&amp;gt; more films than you could possibly watch in your lifetime&lt;p&gt;I was curious if this statement was true...&lt;p&gt;So assuming, 4.4 GB her HD film &amp;amp; 2 hrs long each, you can fit roughly 232 films per TB or 232,000 films total (for 1000 TB), that&amp;#x27;s 464,000 hours of HD content or 53 years (!) back to back.&lt;p&gt;So, yes, that statement is true. Now the next logical question: Has the human race produced 464,000 hours of video content?&lt;p&gt;Let&amp;#x27;s assume there are around 100 cable channels showing content in HD video 24&amp;#x2F;7 (with no overlap, there are more but a lot of duplication). That&amp;#x27;s 2,400 hours of content a day, 876,000 hours a year or 101 years back-to-back worth of watchable content shown each year.&lt;p&gt;But realistically that will be at least 70% duplication (particularly looking at it over several years). So even if we just look at 24&amp;#x2F;7 news and shopping channels which always produce original content, you&amp;#x27;re still talking about easily 200,000+ hours&amp;#x2F;year.</text></item><item><author>krrrh</author><text>If this is real and can be commercialized it could lead to some pretty devastating fallout for the entertainment industry.

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><parent_chain><item><author>Someone1234</author><text>&amp;gt; more films than you could possibly watch in your lifetime&lt;p&gt;I was curious if this statement was true...&lt;p&gt;So assuming, 4.4 GB her HD film &amp;amp; 2 hrs long each, you can fit roughly 232 films per TB or 232,000 films total (for 1000 TB), that&amp;#x27;s 464,000 hours of HD content or 53 years (!) back to back.&lt;p&gt;So, yes, that statement is true.
