AMC is once again leveraging its family of networks in an effort to boost a signature series, this time for the series finale of Mad Men this Sunday.

Sister networks BBC America, SundanceTV, IFC and WE TV will go dark at 10 p.m. on May 17 as viewers bid farewell to Don Draper and Co. A message to mark the long-running series' final bow will appear on screen, likely directing eyeballs toward AMC to watch the conclusion.

Just last month, AMC Networks took a similar approach for the third season premiere of BBC America's Orphan Black, which aired simultaneously across the same networks as a means to provide the underrated sci-fi drama more exposure.

Additionally, AMC will air every episode of Mad Men chronologically beginning this Wednesday at 6 p.m. ET.
