In the fall of 2005, Apple added direct podcast support to iTunes. To normal people, this was what put podcasting on the map. Instead of fiddling around with RSS URLs, third-party apps, and special playlists, users could now find and subscribe to podcasts very easily from within iTunes itself. There’s been a lot of criticism of how Apple has allowed iTunes to grow into an unwieldy behemoth of an app, but I don’t think anyone complained about the addition of podcasts. It was both useful and well implemented.
The Apple ecosystem has changed a lot since 2005, but the essence of Sherlocking is the same: sometimes Apple’s solutions cover the basics, leaving room for third-party developers to thrive; other times, they really sherlock a third-party product with a much better integrated solution. As Drang notes, though, Apple’s podcast Sherlocking in 2005 didn’t have the same result with the Podcasts app in 2012, which has left plenty of opportunities for developers of third-party podcast clients.
