The latest documentary from PBS Off Book is all about logos. Logos surround us in digital and physical space, but as consumers, we rarely examine the thought and artistic thinking that goes into the design of these symbols. Utilising a silent vocabulary of colours, shapes, and typography, logo designers give a visual identity to companies and organisations of all types. From cave painters to modern designers, artists throughout history have been reducing the complex down to simple ideas that communicate with the world. Today, logos can be as tiny as 60 x 60 pixels or as big as buildings. Short and sweet, whether you’re a designer or a consumer, the vid makes for interesting viewing. Off Book is a web-original series from PBS that explores cutting edge art, the artists that make it and the people that share it online. You can see more episodes on the Off Book YouTube channel.
