Check out her list of 10 Christmas commercials from the '70s and '80s. The classic remains the Folgers ad where big brother Peter comes home for Christmas, but there are other greats, too. (Underoos! Christmas Crunch Berries! McDonald's gift certificates!)
In the Peter ad, I notice that 1982 was still the era where they didn't cast blonde babes of approximately 26 years of age to play moms of college students--the mom is frumpy and momlike. I miss those more realistic casting choices.
