Sense: noun/1
For noun sense 1, podcast is the normal word for an audio programme released online for people to play when they choose. A radio show is broader: it may go out live first and may never be offered for later listening. Audio series is useful when you want to stress a set of linked episodes, but it sounds more descriptive and less everyday. Webcast often suggests live internet delivery and can include video, so it does not fit every podcast. Programme is the broadest word of all and needs extra context to show the online audio format. You can follow a history podcast every week, hear a radio show at noon, or watch a live webcast of a company meeting.
Etymology
Podcast was formed in modern English from iPod and broadcast. At first it referred to audio programmes copied to an iPod or similar player, but the meaning soon widened to any online audio show that people can download or play on demand.
