From a logo design perspective, the United States should adopt Chinese. For logos that are the first letter of the entity, the designer has to do something special to distinguish it from all the others using the same letter. This came to me watching a rapper in a video wearing a baseball cap with a “C” on it. At first, I thought Chicago Cubs, but then I recalled their logo is a very simple “C” and did not have the wishbone at the left. Running through baseball cities in my head, I realized it was a Cincinnati Reds logo as it was a red cap with a white letter. After some Googling, I see I might have been thrown off by another Chicago team, the Bears. Their logo is the same C I saw but in red rather than on red.
I have the same trouble with the Atlanta Braves and University of Alabama. As local people are often fans of either, I more frequently see them. And fail to correctly identify them. (Though probably I should have gone with Green Bay and UGA.)
Logo confusion is bad enough for a designer. Logo confusion for other sports teams seems like a budding trademark war. The whole point of a logo is to be distinctive and recognizable. There is only so much one can do with a letter. The English alphabet only has 26 letters. Too much modification takes away the form of the letter until it no longer represents an acronym of the name.
A solution to too few letters could be for the United States to adopt Chinese. With over 6,000 characters, there are plenty more from which to choose. I cannot see that really happening any time soon, especially for this reason.
The look on some people’s faces for suggesting it could be entertaining.
