The Videographer's Apprentice

More than once I've read, on-line, the statistic that every minute 60 hours of video footage are uploaded to YouTube.  I find that number shocking.  I realize that YouTube has millions of users, but even so it seems like a lot of footage.  I think the "does not compute" part of my brain is mainly transfixed on the idea that there will always be more footage on YouTube than any single person could consume in a lifetime because the fire hose can't be shut off, and the influx is bound to increase over time.  I've had a few thoughts on the matter:

• Take a baby born today, with an assumed lifespan of 75 years.  Wait around for 7 days, 15 hours.  BAM!  They've already had an entire lifespan-worth of video footage uploaded, assuming they watch non-stop for the rest of their life.  Sleep is not an option.
• The last HD video I produced weighed in at 46 MB per minute.  Assuming that is a typical file size, every minute YouTube takes on 164 GB of data.  In a single day that's 236 TB of data.  Over a year they're logging 86 PB (that's PetaBytes, or 86x10^12)!  Where are they keeping it all?  At this rate won't the Google data center eventually have to occupy all available space on Earth just to host our inane videos?
• Assume that American television has 100 channels producing original programming.  (I think that's generous, but just assume.)  Assume that in a given year there's original content for 6 months of the year, and the original content is aired 6 days a week, and it amounts to 9 hours each day (morning, daytime, and primetime).  This means the professional content being broadcast in American each year is around 145,800 hours.  YouTube receives an equivalent amount of content every 40 hours!

It's a mind-boggling amount of video content.  It seems like a real waste of resources right now, but I expect it'll come in handy some day when we start sending people on interstellar exploration missions.  At least they'll have plenty of viewing options to choose from on the seat-back monitor as they make their way to Alpha Centauri.  Care for some peanuts?
