Grey's Anatomy [SEP] Introduction
Justin Chambers, who played Dr. Alex Karev, left the show during this season. "Grey's Anatomy" is the longest-running scripted primetime show currently airing on ABC, and the longest scripted primetime series carried by ABC. As of February 28, 2019, it was the longest running American primetime medical drama series. The series was most recently renewed for its seventeenth season. Its success catapulted longtime series regulars including Pompeo, Dempsey and Oh to worldwide recognition; they were among the top 5 highest-earning television actors in 2013. While the show's ratings have fallen over the course of its run (it was once among the overall top 10 shows in the United States), it is still one of the highest-rated shows among the 18–49 demographic, and the #3 drama on all of broadcast television in the United States.
