All eyes will be on AMC Sunday night as the network airs Mad Men‘s series finale. To make sure of it, AMC’s sister networks (BBC America, IFC, Sundance and WE) will suspend regular programing for an hour beginning at 10 p.m. ET on Sunday, instead sharing a special message commemorating Mad Men, the network announced Tuesday.

“Turning AMC over to Mad Men and airing every episode of every season as a lead-in to the finale on Sunday seems a fitting way to continue celebrating what this series has meant to the fans, to television and to our network,” said AMC President Charlie Collier in a statement. “We are also enormously appreciative of our sister networks who are paying tribute to this remarkable program that has had such an impact on our entire company.”
