Evolution of Brand

Here is a great visual comparison by Stock Logos of some of the world's top brands' original logo vs. their current logo.  Many of the companies logos have evolved to be similar to their original brand, and some have decided to change direction completely.  What is missing from this  chart are the intermediate logos which in many cases show how the logos didn't jump to seemingly unrelated ideas, but actually evolved over time to become what they are today.

Two examples of this would be the Shell logo

...and the Mazda logo
