Sandvine has released the latest version of their Global Internet Phenomena Report and the insights are many.

For example:

• Video streaming is almost 58% of total downstream volume
• Netflix is 15% of total downstream volume
• Youtube is 11% and Amazon Prime is 4%
• BitTorrent is almost 22% of total upstream volume
• League of Legends is 26% of global gaming traffic
• Fortnite is 15% and Minecraft is 7%

• Facebook is 38% and Tumblr is 5%
• Spotify is 33% of global audio streaming traffic

My take: interestingly, Netflix videos have the smallest file sizes, followed by Prime Video and then iTunes. I wonder if that could somehow be part of their success; imagine what their share of internet traffic would be if their file sizes were double or even ten times larger.
