Podcasting has been considered a converged medium.
Other names for podcasting include “net cast”, intended as a vendor-neutral term without the loose reference to the Apple iPod. This name is used by shows from the TWiT.tv network.
Podcasting, once an obscure method of spreading audio information, has become a recognized medium for distributing audio content, whether for corporate or personal use. Podcasts are similar to radio programs in form, but they exist as audio files that can be played at a listener’s convenience, anytime or anywhere.
The first application to make this process feasible was iPodderX, developed by August Trometer and Ray Slakinski. This shift occurred as a result of the evolution of internet capabilities along with increased consumer access to cheaper hardware and software for audio recording and editing.
