After watching The Art of Logo Design I found it interesting that the approach of designers has remained consistent and how logos were created for people who were unable to read. It’s so simple it makes sense. This was a way for people to identity themself (merchants and their specific trade).
As designers we want to be the extension and expression of the client. You want to evoke the appropriate reactions which shows the importance of what you are representing.
In the section by Chermayeff and Geismar they mention how important it is to be simple, appropriate and memorable. A simple and small change like the red O in Mobil can make it timeless. In the following section Design Process by Kelli Anderson she expressed the importance of iterations. I now see why It’s important to just get an idea on paper and start somewhere.
I agree with your opinion. Yes, the logo is simple but meaningful, and it is very important for customers to remember the brand.
