Is advertising clutter getting worse?

Or are the media just getting more diverse? Whenever this topic comes up, I bring up how cluttered with ads the physical urban environment of a century past was. In the days before electronic media, but after the emergence of commercial brands, there was a time when every square foot of public space seemed like a potential ad medium.

These Retronaut photos of NYC's Times Square, circa 1900, are a good example of that.
