Bogus estimate of amount of Video creation? (Score 2, Interesting)

Did anyone else blink an eye at TFA's estimate of how much data CREATED this year? From TFA:

Internet users will create 161 exabytes of new data this year, and this exaflood is a positive development for Internet users and businesses, IIA says. An exabyte is 1 quintillion bytes or about 1.1 billion gigabytes. One exabyte is the equivalent of about 50,000 years of DVD quality video.

So, 70.5E9 Hours of video? So, 1 billion people each created 70.5 hours of video worth of data? That's pretty impressive, to the extent that I question the 161 Exabyte figure for internet users. If they include scientific data collection, I'd buy that number, but that doesn't effect our internet; have their own internet, internet 2. Anyone else have a way to explain the data creation figure they quote?
