As we’ve previously discussed, there were outdoor ads as early as the days where farming was the main source of industry in America. But the field (no pun intended) didn’t see a true expansion until the invention of automobiles.

It stands to reason of course. Once cars came around, traveling became more accessible. Before, it wasn’t likely that the average citizen would travel beyond the parameters of their hometown. If they were, they likely were intent on moving to a new place, and more often than not, weren’t planning on returning.
