Bill Bernbach invented the creative team in the 1960s, pairing copywriters and illustrators to develop advertising solutions. This improved quality by allowing two perspectives to find richer solutions without fear of criticism. This started the practice of brainstorming as it is known today.
While the creative process at advertising agencies is largely unchanged, the world has changed profoundly. The new creative needs to be updated by following online channels, communities like Behance that showcase work in many fields, and sources on product design, architecture and more. The new creative also needs to be code literate since websites now surpass TV as how people interact with brands.
