Think of them as YouTube, and the foam as views, except they would be buried in foam.
Remember when we thought the world's computer systems would collapse because of the Y2K bug, and planes would fall out of the sky? Congrats, you're a decrepit old person, but it should help you understand how Psy almost melted YouTube's ability to count views. PSY's video surpassed the mind-bending maximum view-count number the folks at YouTube assumed they would never see: 2,147,483,647.
The irony of news about something being seen so much being posted on Google+...
Two billion, one hundred forty-seven million, four hundred and eighty-three thousand, six hundred and forty seven views. Well, more now.
Why 2,147,483,647? Well, in computer terms, that's the highest value you can write with 32 bits (i.e. a string of 32 zeroes and ones has 2,147,483,648 combinations, but since one of those is zero, you can only count up to 2,147,483,647). Since that's like two India's worth of views, YouTube didn't think anyone would make anything worth watching that many times.
This is the perfect summation of all YouTube comments, gone meta.
But the South Korean pop revolution that was Psy, doing his horsey dance and screaming at women's butts, was more than just some 31-bit flash in the pan. After all, even his follow-up works, which did not really make that big of an impact, still racked up 762.2 million views for "Gentleman" and 162.3 million views for the new "Hangover," featuring Snoop Dogg.
No, it's not negative. It's not wiping all memory of this from the world. Sadly.
