This post is spoiler-free, unless you consider non-story aspects of the show's premise to be spoilers.

The surprise TV hit of the summer is Mr. Robot, a USA Network series following a bug-eyed, hoodie-wearing New York City security analyst and (it goes without saying) hacker. In this summer of Ashley Madison hacks, Donald Trump lunacies, and now stock market worries, perhaps we shouldn't be surprised that a show about subverting corporate and political forces is a big commercial and critical success.

Not only is Mr. Robot unusually accurate in its depiction of hackers and coding, it feels real in other ways: angst about Facebook mediating our relationships, nonchalance about iPhones and Androids doing the same, a creeping fear that nothing is truly secret, and workplace derision of the last guy still using a BlackBerry. It's the first show to reflect back at us the world we see when we peer into our laptop screens.

Mr. Robot's attention to detail extends to the show's iconography, especially its brands and logos: the series is populated with fictional corporations and vigilante groups which seem as if they could exist in reality. And in some ways they do: series creator Sam Esmail was personally involved—"to a fault," he says—with developing these invented brands from elements of genuine ones.

With the series finale coming this Wednesday, let's take a look at the four most interesting logos: Mr. Robot computer repair, the ominous conglomerate E Corp., network security firm Allsafe, and the mysterious underground hacker network fsociety.
