The final seven episodes of Mad Men haven't even began yet, and the thought of life without the show is already too much to handle. But if AMC had followed through with considerations for a spinoff, such preemptive mourning wouldn't be entirely necessary.
The network once considered creating a spinoff series with either Sally Draper or Peggy Olson, according to Lionsgate COO Sandra Stern. She told THR in a fantastic Mad Men cover story:
“When we first started negotiating with AMC, one of the things they wanted was a spinoff. We talked about doing a contemporary one. Given the fact that [Mad Men] ends nearly 50 years ago, most of the characters would be dead. Sally was the one character young enough that you could see her 30 or 40 years later. There was a time we wanted a Peggy spinoff, too, and, a la Better Call Saul, a minor character going off to L.A. Matt wasn’t comfortable committing to a spinoff.”
Even though it wouldn't have given us the much-desired Sally Draper Woodstock episode, giving her her own show is the most intriguing of the two ideas. Her character has grown the most in recent seasons and would allow for even more exploration similar to Saul Goodman's spinoff (except, you know, in the future).
But for now this is little more than a Don Draper fever dream.
