So, which character's "tagline" is your tagline?
Everything You Say Is An Ad For Yourself™
In the ad industry, whenever you present a new campaign to a client or a prospective client — whether it's 1960 or 2013 — you close the dog & pony show with the campaign's tagline, slogan, motto, kicker, etc.
AMC created a Facebook page of Mad Men Mottoes, which presents the major characters' more memorable catch-phrases as title boards — exactly how a creative director would (or at least should) present a product's new tagline.
I've got my one favorite picked out that best reflects my beliefs (It's a Roger Sterling).
So, take a look. I've only included what I think are the strongest slogans for each character. If you want to see them all, go to Mad Men Motto.
As an ex-copywriter, I'm very disappointed AMC hasn't done this for brash copywriter Michael Ginsberg. He's certainly rattled off some doozies.
