Podcasting

Narrowcasting is the dissemination of information to a specialised audience, rather than to the broader public-at-large; it is the opposite of broadcasting. It may refer to advertising or programming via radio, podcast, newspaper, television, or the Internet. The term "multicast" is sometimes used interchangeably, although strictly speaking this refers to the technology used, and narrowcasting to the business model. Narrowcasting is sometimes aimed at paid subscribers, such as in the case of cable television.

Podsafe is a term created in the podcasting community to refer to any work which, through its licensing, specifically allows the use of the work in podcasting, regardless of restrictions the same work might have in other realms. For example, a song may be legal to use in podcasts, but may need to be purchased or have royalties paid for over-the-air radio use, television use, and possibly even personal use.
