Podcasting has taking the word by storm over the past few years. Almost everyone has a portable media device and they are not all being used for downloading music.
Internet Marketers, Teachers, Authors, Musicians are making their voice be heard by podcasting. It is the new way to reach their target audience. And they can reach millions all over the world instead of just hundreds in their own community. Podcasting allows you to have your own radio show and you become an expert in your field.
You may say, "What is podcasting?" According to Wikipedia, it is a collection of digital media files which are distributed over the internet. They are then downloaded via your computer or onto an mp3 or the every popular iPod.
The reason it is different from a traditional download from someone's website, is because a podcast is automatically updated by syndication or RSS feeds. People subscribe to your RSS feed and are automatically updated every time you have a new podcast available. Many podcasters record 15-30 minute segments and range from once a week to twice a month.
Now your voice can be heard on someone's computer, in their car, or while they are exercising. You can reach millions with your podcast.
