Logos are the most obvious public face of your organization, app, product, you name it. While they are not the reasons most people buy your product, there is power in a logo.

And while those companies have made slight changes to their logos and branding through the years, the changes were minute enough that you barely gave them a second thought, if you noticed it at all.
