Beginning a few years ago, every game of the NCAA Men’s Basketball Tournament — also known as March Madness — has been streamed online. Last year alone, 13.7 million hours of streaming games were watched. And with more and more people embracing online video each day, this year’s total number of hours is expected to be even bigger.

The question we had was, How much bigger? So we decided to crunch some numbers and come up with a prediction for total hours of streaming during this year’s tournament. The total we came up with: a whopping 17,786,648 hours, or the equivalent of nearly nine million movies. Will we be right on the money? Probably not. But it will be fun to find out.
