All Chicago shows still pull in above 5 million viewers each week and each show reaches to 7-10 million viewers after DVR and 3 days are added in, so the ratings are not and if they were looking at getting out of the franchise they wouldn’t have for one ordered Chicago justice go series and forntwo they would not have renewed three of the franchise they would have made it where the current season finale would have been written as a series finale first but Chicago Fire is going into its sixth season, Chicago PD isngoing into its fifth season and Med is going into its third season on the air coming this fall.
Chicago justice did start just earlier this year around March 5th is when it first started and the other three have had a whole fall season to deal with ratings while justice has only had maybe two months to deal with getting strong ratings and the show does get some bad ratings here and there but every show does just look at Grey’s anatomy for example when it first started it was getting 20 million viewers every episode and now it even struggles to get 8 million viewers live and it is still going strong and the Chicago franchise top NBC’s best rated shows, fire is second best on NBC, pd is third while Med is about 4th and justice is sixth.
And for Chicago Justice, my thoughts is that they are waiting for the finale ratings to come in first.
