There's a new form of podjacking. It happens when the podcaster, during a live recording, invites guests to call in to a conference call, the call starts and is being recorded, and then one of the participants puts the conference call on hold. Hold music commences, and the podcast degrades into unlistenability. Jerry Michalski experienced this on his Jan. 23, 2006 podcast, which you can find on this page. A show two weeks later was "rescheduled as Call 75 due to 'music on hold' issues." There's a business opportunity for the confererencing service that can automatically detect and mute hold music.
