A podcast is a multimedia file that is distributed by subscription (paid or unpaid) over the Internet using syndication feeds, for playback on mobile devices and personal computers[1]. Like 'radio', it can mean both the content and the method of broadcast. The latter may also be termed podcasting. The host or author of a podcast is often called a podcaster. Though podcasters' Web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital audio formats by its ability to be downloaded automatically using software capable of reading feed formats such as RSS or Atom. http://en.wikipedia.org/wiki/Podcasting

Something like a newscast or TV program that can be uploaded into an MP3 player/IPOD. All the major network news programs have theirs online for download/upload. Same with TV shows like Desperate Housewives. If you have the time and space to put it on your IPOD/MP3 player, they have it there for you! Hope this answers it. Not sure why nobody else did...

Hope this helps. Definition of: podcast (iPOD broadCAST) An audio broadcast that has been converted to an MP3 file or other audio file format for playback in a digital music player or computer. The "pod" in podcast was coined from "iPod," the predominant portable, digital music player, and although podcasts are mostly verbal, they may contain music. Using the RSS 2.0 syndication format, podcasts are made available to subscribers just like news feeds. The client program that captures the audio feeds and synchronizes them with the music player is a "podcatcher," such as Curry's own iPodder, available at www.ipodder.org. See syndication format and vidcast. Podcasting Anything and Everything Podcasting is not just for on-going broadcasts, rather the term is used for recording anything and everything to be played back in a digital player.

A podcast is basically an audio program created and distributed in a manner suitable for listening on a computer or mp3 player. Podcasts are typically created as a series of programs, intended to be subscribed to. If you ever wanted your own radio program, a podcast is the way to go. Now, podcasting has evolved into a mass method of distributing audio content, including school lessons and more.

Wikipedia, defines Podcast as a... collection of digital media files which is distributed over the Internet using syndication feeds for playback on portable media players and personal computers. The term, like "radio", can refer either to the content itself or to the method by which it is syndicated; the latter is also termed podcasting. The host or author of a podcast is often called a podcaster. The term "podcast" is a portmanteau of the words "iPod" and "broadcast", the Apple iPod being the brand of portable media player for which the first podcasting scripts were developed (see history of podcasting). These scripts allow podcasts to be automatically transferred to a mobile device after they are downloaded. Though podcasters' web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital media formats by its ability to be syndicated, subscribed to, and downloaded automatically when new content is added, using an aggregator or feed reader capable of reading feed formats such as RSS or Atom.' Do's & Don'ts on Creating a Great Podcast 1. Keep your Podcast Short. 15 -30 min is a great length.. Now, if you have loads of great content and can keep the listener's attention for a longer duration, then go for it. With a strong guest or subject, 45 min -1 hour is possible. 2. Know your Target Audience. Identify your target audience, then design your podcast to capture their interest. Create a podcast with your listeners needs in mind. Once you know your target audience, all the other ideas should be modified to suit that specific market. 3. You are Not making a commercial. Creating a podcast masquerading as nothing more than an advertisement for your business is self serving. The listener will see right through that and will most likely stop listening. Podcasts are meant to be information intensive and you should be supplying content that is rich and relevant. Let the listener decide if you are knowledgeable about a subject and they might come knocking at your door for your services. 4. Be Relaxed. The most effective podcasts I have heard are where they're having a good time, and it really shows. 5. Keep it Interesting. Create short segments that are diverse. Appropriate music and sound effects between segments aid production values and help keep moving things along. MTV is our generation, whether you agree or not. Audiences like it varied. Fast. And with substance. 6. Be organized. Don't ramble. Flipping on a mic and babbling for an hour is the biggest mistake a podcaster can make. Take the time and prepare a script or at least a rough outline of what you'll be talking about. If your podcast is an interview, prepare your questions in advance. Your guest should be forwarded a copy, that way they can be confident and coherent. You don't have to stick to it verbatim, but it should help keep your podcast from becoming chaotic and wasting the listeners time. If you are not interviewing, write out an agenda taking note points of what is to be discussed, this will ensure the podcast moves along quickly. 7. Stuff, stuff, stuff as much good information as possible into your podcast. People's minds move faster than your mouth. Pack your podcast full of quality content. Move at a quick pace. 8. If you've got quality content, podcast regularly. Quality is much better than quantity. Listening to an excellent podcast every three months, is much more appealing than a mediocre weekly segment. When the listener commits to a podcast by pushing 'Play', you have both their attention and their trust. Be wise. Treat them with respect. Develop your audience. Let them know you. 9. Use professionally recorded audio. Seriously folks, I can't stress this enough. If the audio sounds like it's at the end of a tunnel it can ruin a podcast. Using your computer with it's built-in mic just won't cut it. Care must be taken to record broadcast quality audio that needs to be seamlessly edited, and processed. Use the services of a professional recording studio with quality mics, preamps and processors. After all, this is their expertise. 10. When doing interviews, know your subject. Do your homework. Be prepared. 11. Stale topics. Do something fresh. With so many interview subjects , approaches and topics, it's a challenge to find fresh subject matter and ideas. 12. Be natural. Be yourself. 13. Be prepared to '86' a show. A bad show should not be aired. Whatever the reason. 14. Background music and musical cues. Music can be a bonus to a podcast. Decide when to use it. Judiciously. 15. Identify yourself. Date. Issue Number. Topic. Guest, etc... at the start of the show. If you have a list of email addresses, links, and so on, save it till the end of the show. Get on with the podcast. 16. Market that sucker. Publish your podcast on as many sites as possible. Make it easy to subscribe. Promote yourself.

Taking your iPod and "casting" it out over a surface of water, trying to get it to "skip" as many times as possible before either making it safely to land, or sinking into the watery depths, never to be seen again.
