Fun fact for TV shows on the bubble: You don't have to have stellar ratings to get renewed. Yes, Nielsen numbers are a big part of the decision-making process when the broadcast networks choose which series to ax and which to keep, but they aren't everything. Each year, plenty of shows which fair modestly in the key demo squeak by. Scroll through the TheWrap's gallery to see the lowest-rated TV shows of the 2017-18 season -- so far-- that got renewed. (Of course we counted "Brooklyn Nine-Nine" here, because of that last-minute NBC pickup). All ratings in this story come from Nielsen's "most current" data stream, which includes a week's worth of delayed viewing where available. Least-viewed is first, most-watched last.  And, yes, there are ties. Also Read: 16 Highest-Rated Canceled or Ending TV Shows of 2017-18 Season – So Far (Photos)
