Channel 4

9 hours 10 minutes

I am surprised at the amount of documentaries actually on these two channels, I thought at the most there would be around 30% of straight documentaries (not including other factual programming like the news or game shows). I also think it is interesting that both channels share nearly the exact same  amount of screen time for documentaries. 37.5 must be the magic number.
