Copy became fashionable again in the 1950’s. Where brands used to identify a product, they were now to be found everywhere. The need to look good on a brochure or letterhead meant that designs went back to the symbol and copy formula, featuring strong colours and eye-pleasing designs.
The standard of modern screens and digital printing means that logos have more freedom than ever. They still need to be adaptable though, take the Google logo, comes in many different disguises, but is still unmistakably Google.
