Around what year did the invention of automated, recurring audio delivery occur?

Answer

2003

If the invention of the platform is strictly defined as the initial functional system that enabled the automated, recurring delivery of serialized audio content directly to listeners, that achievement took place around the year 2003. This invention was the result of the technical partnership involving the work of Adam Curry, who provided the engine for linking feeds to players, and Dave Winer, who established the structural blueprint via the RSS enclosure tag. Although the terminology ('podcast') wasn't formalized until 2004, the core protocol that still underpins virtually all modern podcast delivery mechanisms was operational in 2003, making it the key invention timeline for the platform architecture.
