The number of YouTube videos employees watch is not exactly the kind of number tracked by corporate analysts or released by companies. Suffice to say, on the evidence of being a human being in the white-collar workforce, I have long been sure that the number of YouTube videos watched on the clock is astronomical, belonging to the category of numbers so large that you should write them like this: 107.
But it's hard to calculate. There are too many confounding variables. YouTube says it streams more than 4 billion videos per day, with about 40 percent coming from the US, so 1.6 billion American streams each day. Let's assume there are 300 million Americans who all watch exactly the same amount of videos each day. That'd be five per day per person in the United States. But how many come outside of work? How many come from the country's 55 million white-collar workers during the hours between 8 and 6pm? We just can't know.
