Hey there LegendMan!
So, based on my reading of this passage from above, I see how this man watches (tv) and that the users that watch it may know a little more.
So, based on my information, it seem's like that answer could be "<span>Viewers know more about television than those who broadcast it." This may sound weird, but it was clear in the passage that this was the case.
Hope this helps.
