As you scan down the list, you will experience a several generations of American culture. These are awesome.

"...It is, of course, a challenging and somewhat presumptuous enterprise to reduce a century’s labors to a Top 100 list. It is not difficult, however, to establish criteria. To be included, a campaign could qualify in one of three ways:

1) If it was a watershed, discernibly changing the culture of advertising or the popular culture as a whole.

2) If it itself was credited with creating a category, or if by its efforts a brand became entrenched in its category as No. 1.

3) If it was simply unforgettable..."
