I think seeing historically uncommon/rare events unfold also falls under gratifying one's intellectual curiosity (though I admit this might be a stretch in this particular story). Additionally, there are multiple stories that pop up (once or twice per day, from my anecdotal experience) that are also stories that'd be covered on TV news.
