Atomic unit of media consumption..... whatever it is

I have no idea what is the atomic unit of media consumption... atomic unit was in my chemistry books if I remember correctly. But what I know is Google is seriously planning a new news venture. First came how much Google news was worth, then wiki style news and now this atomic level consumption... whatever. Nevertheless a fresh Marissa video, enjoy with guilt>>>>>>>>
