Every TV show has a certain style to it, especially its art and graphics. They are what set the show apart aside from the characters and the show in its entirety.
When a TV show has great, unique graphics, images, and artistic style, you recognize it all right away. Let's look at Mad Men's graphics and style for a minute. The red and white font colors (though "men" sometimes appears in black), and the sans serif typeface, are not unique to Mad Men. Other shows have used that typeface and certainly those two colors. However, when put all together, it becomes something special to Mad Men, especially when you look at how the show's name is split between the two colors (notice the emphasis on the "Mad" since it's in red?)
What is really special about the artistic style of the graphic design for Mad Men is the B&W figures, such as what appears to be Don Draper in the main image of the show. We also see a faceless, ambiguous, B&W man falling during the opening title sequence, seen here.
These faceless, 2-dimensional characters really don't stretch or further the artistic world but they are special, unique, and downright cool. No other show utilizes this style of art and it is easily identifiable by anyone who has even heard of Mad Men. These figures bring something incredibly unique to the table as well, we are able to become those figures since they have no faces. The graphic design team who created these figures made them faceless for a reason (and not because they couldn't draw faces); they wanted viewers to be able to be in the place of those "people".
This is what great, unique, and creative graphic design can do for a company, TV show, movie, or anything else, really.
A great professional graphic designer can identify some nugget of uniqueness in a project and build that to be a "competitive advantage" for a design; that objective was met and exceeded by the team who made this art.
