Nick Quah, the founder and writer of the podcasting industry newsletter Hot Pod, talks with Recode's Peter Kafka about where podcasts are headed next. Quah says two events in 2014 — Apple's decision to make the Podcasts app a default one on iOS and the success of the true crime show "Serial" — are responsible for the explosion of interest in podcasts over the past few years. His newsletter, which currently reaches about 11,000 inboxes, is aimed at people who work in the growing industry and has become his full-time job, along with several side hustles. Quah also discusses how Apple's plans to share more data about podcasts' audiences with their creators will be good in the long term for most shows, but could spell bad news for some of them.
