In 1934 DC comics was founded by Malcolm Wheeler-Nicholson.  The current logo was created by a brand consultancy firm called Landor Associates.  DC comics have been around for quite some time. Unfortunately, a consistent logo design has not.  There are so many different variations that brand recognition is lacking.  Out of all the logos I do like the newest the best, simply because it isn't inside a circle. For some reason the circle design reminds me of something that would going on the side of a pair of sneakers. This is probably because one of the logos for Converse is round with a star in the center.
