I think the Apple logo is a great example of an identity system. It's very simple, yet effective. The identity illustrates the name of the company without having to type the name underneath the image. It is a universally known and easily recognizable logo. It's great for advertising as well. You can often spot Apple products in movies or tv shows by recognizing the Apple logo in the background. You don't need to read a name to know it's an apple product, the image is all you need to see. The logo was created in 977 created by Rob Janoff .
