    Notes on slide 1

    Someone puts audio files on the Internet and creates a feed for subscription purposes. The feed checks for updates as they are uploaded to the Web, “Podcatcher” software can be used (such as iTunes) to organise and then download the new podcast installment to your computer or mp3 player for portable listening!

    First the Internet, then the Web, then blogs, along with RSS technology, then the adding of audio files to blogs (“audio blogging”), then podcatcher software…and finally podcasting as we know it today….basically.

    On the request of a user, the software was configured so that audio files could be included. The RSS aggregator picked this up and allowed audio files to be syndicated

    Adam Curry – “The Podfather”

    The prototype for iPodder did a very basic job of collecting audio files from different sources on the Internet, and automatically loading them onto iPods so one could listen to them at their leisure. Curry named the code iPodder, and he released the first version to the public on August 15, 2004.

    Paris Hilton!

    US statistics

    Quite an increase and set to grow even more

    Podcasting can be tricky when it comes to copyright. As they are considered public broadcasts, like any radio show, etc. you have to be careful not to use copyrighted music ro spoken word. The law is trying to catch up to the technology!

    A computer! Essential for creating podcasts…

    Apple’s Garageband software makes it easy to create podcasts – it comes as standard with Macs. Also integrates with iTunes for ease of use.

    A microphone! But you can always use the built-in mic found in your computer if necessary. The sound quality may not be as good….

    A pre-amp for the microphone, though it is not essential
