2014-15 Update: ABC made its two-hour Shonda Rhimes drama block into a three-hour Shonda Rhimes drama block, and it became one of the biggest nights on television. Grey's Anatomy was somehow just barely down in Plus in the move to 8/7c, which allowed them to effectively replace the awful 8/7c occupants with another Scandal-sized player in 10/9c's How to Get Away with Murder. Things came undone somewhat in the spring, when Murder replacement American Crime (69) tanked and Scandal infamously shed 1.2 points in just five episodes. But ABC is hoping it'll all come back together when Murder returns to the saddle this fall.
Notable midseason replacements:
- ABC brought in Dancing with the Stars (124) in the winter of 2006, generally airing it from 8:00 to 9:30.
- In the writer's strike season of 2007-08, Lost (162) filled in for awhile at 9/8c before moving to 10/9c after Grey's returned.
- Private Practice aired the second half of its 2008-09 season at 10/9c, averaging a 127. The short first season of Scandal averaged an 85 at the end of the 2011-12 season.
