YouTube’s practice of taking down copyrighted content after it’s been uploaded and accumulated millions of views has always seemed a bit illogical. Why not cut out the possibility of legal issues altogether? Well, because YouTube, let alone Google, simply can’t afford to prescreen videos. To review the 72 hours of video uploaded to YouTube every minute, 199,584 employed professionals would be needed. That manpower alone would cost $36.8 billion. Google made $37.9 billion last year. Even sweatshop labor can’t make an operation like that affordable.
