I spent a lot of those hours with Twitch open in a tab on my browser but muted. I certainly did not spend 100 more hours watching Twitch, or even listening to Twitch. I place the blame for more hours spent firmly on Twitch Drops.
Last year it was 214 hours over 85 days, so more time on more days I guess. I was in for 325 hours total viewing, over 138 distinct days.
