I love podcasts. I listen to them on my commute. I listen to them while I walk my dog. I listen to them when flying. There are so many great ones out there - all different lengths for whatever time I have (5 min. or 1 hr.). For me, I can learn more about marketing and communications or I can learn more about technology or escape down another road of personal interest. I'm definitely not the only one.
Whatever I'm listening to, I hear the same sponsors over and over. In a golden age of amazing content of all types, there's plenty of room for companies to advertise on podcasts.
