Helvetica. It's a widely used sans-serif typeface created in 1957, little known by many people. Which is sad, because it's possibly the most beautiful and influential font family in modern history.
When it was created, it took the world by storm. Before Helvetica, advertising and writing was entirely composed of fancy, grotesque, cursive fonts (just google advertising in the 1940s). Helvetica was so neutral, it completely redefined the world of text and created a whole new genre of fonts.
Now, it's been overtaken by copycats and lookalikes, such as Arial, which has skyrocketed to popularity since Microsoft has adopted it, leaving Helvetica in the dust and unknown to the modern world.
Helvetica made history. Let's fight back.
