According to a report from Cisco on consumer internet traffic, online video is going to be massive.  By 2018, over 75% of all traffic is going to be video based.

Globally, IP video traffic will be 79 percent of all consumer Internet traffic in 2018, up from 66 percent in 2013.

It would take an individual over 5 million years to watch the amount of video that will cross global IP  networks each month in 2018. Every second, nearly a million minutes of video content will cross the network by 2018.
