This document discusses the evolution of agency structures from siloed traditional and digital departments toward more integrated models. Traditionally, creative departments were separated into traditional areas like print, TV, and radio versus digital areas like websites and banners. Production was also separated. However, lines began to blur as digital grew and clients wanted integrated ideas. Now, agencies are moving toward models where digital expertise is at the heart of creativity and silos have fallen, though many are still adapting their processes to the new integrated landscape.
