Are we headed back to the circa 1900 era when there were ads plastered everywhere?

(look at some old photos of cities; they were all over any flat surface)
Something else interesting is that these ads of yore were often for "snake oil" (all sorts of medical remedies that did nothing). They were put out of business with the FDA. Today, what are a lot of ads for? Lifestyle enhancement drugs!
Round and round we go....
