Ever noticed that the "N" in 7-Eleven is lower case? Well, neither did I until my supervisor pointed it out to me. Ever curious, I decided to investigate the possible meaning behind this whole branding exercise...
There are several reasons that are floating about on the internet:
1) It's for Feng Shui or Numerology reasons; the lower case "N" as a magnet for good luck and fortune.
2) An all upper case "Eleven" appears harsher in branding, so the lower case "N" was introduced to give a softer, graceful look to the company.
But thank god for me talking up a PhD just to know about this...
