Whenever a person listens to Podcasts, the idea of producing one might crop up. Many podcasts sound like normal radio shows but the person needs to ensure that he / she does not run out of topics or ideas which would prevent them from choosing something about which they feel intensely. One can create and model their own podcast along the lines of popular podcasts. This includes the duration of the podcast, the rough outline of each episode as well as the background music which suits best. In order to create a podcast one needs a PC with a microphone and an Internet connection. Laptop owners however cannot use the embedded microphone as it will also record the ambient noise. If the user wants their podcast to contain video, they would need a webcam.
