According to new numbers from Sandvine, 70% of Internet traffic during peak hours is now driven by streaming video and audio. As Jillian D’Onfro of Business Insider reports:

Netflix, YouTube, and Amazon Video are the top three sources of video traffic, with ~37%, ~18%, and ~3% respectively. Although traffic from Amazon’s video offering still pales in comparison to Netflix’s, this is the first year it broke into the top three.

For context, streaming video and audio accounted for a mere 35% of peak traffic just five years. That’s quite a leap in half a decade.
