The yellow smiley face
If you walked into any Walmart in the ’90s, you would have been greeted with hundreds of smiley faces plastered on signs and uniforms. The old design was so popular that, in 2001, Walmart decided to attempt to trademark it, taking on a company called The Smiley Company, which was using a similar smiling logo.
After a long battle over the course of a decade, the dispute settled in 2016 with both companies maintaining the right to use their respective smiley faces.
