I love these comparisons. Let’s take a look at where N. Korea firing missiles falls on the big three’s list of importance. All of these screens were taken at the same time.
So it looks like Fox finds it most important- big box at the top and the update the story most frequently (4 missiles fired). CNN puts it in top stories, but at the same time Fox is reporting 4, CNN is reporting 2 fired. Finally, even though MSNBC is updating more frequently than CNN with 3 missiles reported as fired, the story is almost an after thought- smallest text in the top stories area.
