Alright, it's all good and dandy to play devil's advocate to everyone, but it would be nice if you didn't mind sharing your definition of "advertising" that dates back to the 1600s and includes "knowing about the existence of vegetables".
By the 1600s, people were letting it be known about wares they wish to sell and whatnot in newspapers; a practice that continues today. This is generally considered the birth of "modern" advertising.
If you want a definition, pick a definition – come up with something on the spot, even. It makes no difference to me.
Just a definition would be nice. Thanks.
