Sam BrannanSam Brannan was an enterprising man who established a general store near Sutter’s Mill shortly after the discovery of gold in 1848. Sutter aimed to keep it quiet to make a fortune for himself and not have to share it. But Brannan knew that a gold rush would soon be on, so he stocked his store with items he was aware that the thousands of incoming prospectors would need.

But to make sure word about the gold got out, he walked down the middle of a street in what would one day be San Francisco, waving a pouch of gold over his head, and cried, “Gold from the American River!”

All in all, a significant day in the history of advertising.
