Just like blogs, podcasts are yet another Web 2.0 offshoot, bringing  content-generation away from centralised sources (i.e., radio,  television) into the consumers themselves. The term podcasting comes from “iPod” and “broadcasting”. However, you  don’t need an iPod to listen to a podcast.  Anyone  with a computer or mp3 player can join in and this post will teach you how.
So, what exactly is a podcast?
A podcast is an audio programme distributed via the Internet. It’s a way for individuals and companies  to create audio programs and  allow users to download, listen, and  subscribe to them very easily.  If  you’re familiar with blogging you can  think of podcasting as “audio  blogging.”
A podcast is different from a regular downloaded audio recording or  streaming audio, however, in that the content-distribution is  automatically done through RSS. The ability to subscribe to  podcasts via this technology allows fresh content to be downloaded to your computer or portable audio  player  (e.g., an iPod). For instance, a regular podcast subscriber would expect the  audio recording to be automatically transferred to his computer (and  portable media player, if available) once there is a new edition or  episode of his subscribed programmes available.
How do I subscribe to BMJ podcasts?
10 of the BMJ journals now have their own podcast channels, where users can listen to interviews and debates on the current topics in their specialist field. All of the available podcasts are listed on the podcast homepage http://podcasts.bmj.com/.
You can subscribe to a podcast with podcast software such as iTunes, Juice or Doppler or you can subscribe  using a web based “feed reader” such as My  Yahoo or Google Reader.  Please read the instructions on their sites for more information.
When you click on the “Subscribe now” button you will be given the  different options to subscribe to the podcast. We have provided “One  Click” links for you to automatically subscribe if you already use iTunes, My  Yahoo or Google Reader as your podcast reader. Simply click on the link and the software or  service will do the rest. If you use a different podcast reader then you  can copy and paste the “Feed URL” into your podcast reader. Refer to  the help on your feed reader for instructions on how to do this.
Alternatively, users can listen to podcasts on a journal’s individual homepage using the tabbed widget (mentioned in a previous post) towards the bottom of the page. Simply click on  ‘podcasts’, select the title that interests you and a media player will  open within the same window (see screenshot below).
