Relevance is a funny thing. Many of radio’s leaders will argue radio’s relevance is proved by its widespread consumer usage. Hogwash. Usage is a temporal thing. It is a byproduct of relevance but it is not relevance. Relevance is relevance. And long-lived goods and services which are not as relevant to me and my life as newer goods and services will be disrupted and displaced by those newer goods and services over time. So never take refuge in being popular. Just ask MySpace.
