"Average" probably means the mean here, not the median. So it's not half who watch more than that. There's probably a big gap between the mean and the median. Nobody publishes the median because that number is published by the ad industry which has no interest in showing the lower median.

TV can be passively watched though while you do other things. Gaming has to be actively engaged with

Is that statistic active watching, or skewed by those that leave it on 24h news or shopping or whatever 24/7?
