The document discusses the evolution of broadcasting from a one-way communication model to broadcasting to the lowest common denominator, to the potential for "perceptive media" - using internet technologies and context to create a more personal experience. It describes early experiments with object-based broadcasting and interactive mixes that allowed users more control and found they had higher engagement, enjoyment and felt the experience was better than traditional radio. Going forward, perceptive media could involve sensors to understand attention and personalization to deliver immersive, variable and challenging stories beyond just screens using tools like IoT.
