The ad is also notable for the way it engages the new technology of television, and tells us it is acceptable to socialize around the little screen at a dinner party.

To read more about Jo Copeland, I highly recommend "Mommy Dressing: A Love Story, After a Fashion," by Copeland's daughter, Lois Gould. Heartbreaking.
