I suspect the stat gets blown out of proportion by people who leave the TV on as background noise. I'll never personally understand having a TV in the bedroom, but I know folks who can't fall asleep without it on.
It's median, but I think there's a similar effect actually. A lot of people "watch TV" as a side activity to something else (like browsing their phone). Alas, I've never been able to multitask as well as my digitally-poisoned peers.
The GP said median, which should reduce the bias of the outliers.
