The technology underlying podcasts is simple–a podcaster publishes mp3 files to an RSS feed, and the listener subscribes to that feed, receiving mp3s whenever the feed is updated. Unfortunately, the simplicity of podcasts makes it difficult to build automated advertising infrastructure on top of that simple RSS model. This lack of rich automated advertising has kept podcasting from flourishing.
aCast is a company that is trying to change that by providing a better podcast experience for both the publisher and the listener. Today’s guest Mikael Emtinger is a creative technologist at aCast, and we discuss the infrastructure around podcasts, and how aCast is trying to improve it.
