washington. i'm brian sullivan. today on "reliable sources," why does bad news always seem to trump good news about obamacare? and speaking of good news on this sunday morning, some hopeful signs for the news business after years of suffering. we will get into that a little bit later. but let's begin with the story that is still baffling the whole world. that's the story of malaysia air flight 370. here are my questions this morning. what lessons have members of the media learned from these three weeks of coverage? and what have we learned about the media? cnn, as you know at home, is still concentrating very heavily on this story for both editorial reasons as well as business reasons. every day i get a spreadsheet with the ratings from the day before. it's circumstance lauted widely at cnn. and every day i wonder is there going to be a big drop-off in the rate sngz because that would mean a decline in the audience's interest in this mystery. well, so far the interest is still very high. these are the total ratings for cnn, fox news, and msnbc from new year's all the way through
