Odd v/s Even

This post about a brand named '7 for mankind' got me musing on something odd about brand names with, or that are, numbers. A quick research will tell you that most 'number brands' prefer an odd number to an even one. (Cases in point are brand names like 3, 9, 7/11, 7-up, 57, 3663 and of course 7 for mankind, to name a few.) Why are odd numbers more memorable? Simple: Even is not odd enough to stand out. Takeaway tip: If you must put a number in your brand name, go with something odd.
