Title:
American_Broadcasting_Company

Context:
On April 14, 2011, ABC canceled the long-running soap operas All My Children and One Life to Live after 41 and 43 years on the air, respectively (following backlash from fans, ABC sold the rights to both shows to Prospect Park, which eventually revived the soaps on Hulu for one additional season in 2013 and with both companies suing one another for allegations of interference with the process of reviving the shows, failure to pay licensing fees and issues over ABC's use of certain characters from One Live to Live on General Hospital during the transition). The talk/lifestyle show that replaced One Life to Live, The Revolution, failed to generate satisfactory ratings and was in turn canceled after only seven months. The 2011–12 season saw ABC drop to fourth place in the 18–49 demographic despite renewing a handful of new shows (including freshmen dramas Scandal, Revenge and Once Upon a Time) for second seasons.

Question:
2011-12 saw ABC drop to 4th in ratings among what important demographic?

18–49 demographic
