Kai Ryssdal: Up next, the humble podcast. We do it. A lot of other programs do it. A lot of audio and video producers that aren’t actual programs do it. In part because it’s just so easy. Producers create the file. Consumers click download, and boom it’s done. The process behind those podcasts, though, is protected intellectual property. This week a small company called VoloMedia was awarded the patent for podcasting. Which is where I say: cue the lawyers. From New York, Jill Barshay reports.
