Podcasting ….a brief History
The concept of Podcasting, rather than its usage, was suggested as early as 2000 and its technical components, the bits that made it possible, were available by 2001 to the technically minded.
By 2003 regular podcasts started showing up on well-known Web sites and software support for this developing medium began to spread around the electronic world
Now you can hardly turn round or look at a blog, wiki or web page without seeing that there is a podcast of some sort attached to it.
First came the sound only podcasts (to be followed very quickly by video podcasts … but that is for another day) , a concept of on-line ‘radio’ but able to be delivered by subscription straight to your sound ‘in box’ and then downloaded, if you wished, to a portable player.
Now there are all sorts of definitive words associated to confuse and illuminate the growing art:
you can :
Autocast (the automatic generation of podcasts from text-only sources)
Blogcast (the blogging Podcast)
Mediacast (any distribution of audio/video media files utilizing RSS)
Mobilecast (podcasting to mobile phones)
Vodcast (video podcasting)
Peercast (peercasting allows live streams to be redistributed by the viewers/listener, greatly reducing bandwidth needs for the originating broadcaster)
Apple were the main players to begin with and the whole movement became synonymouse with ipods and using Apple computers
… a good marketing ploy and it worked well but it doesn’t matter what machine you work on podcasts can be developed on Mac or PC and downloaded to and listen on either platform machine.
The whole concept is really not about just making audio files available over the Internet but is about subscription so that once you have subscribed to a podcast feed you automatically get every update to that feed which is produced. A one stop audio shop !!
Early on it took a number of pieces of software to prepare a podcast. First the podcast itself had to be recorded and saved as an MP3 file…. Then this file had to be used to generate an XML file which had the RSS feed attached to it …. This was then used to generate a url which sat in a web space somewhere so people could get at it and listen to it ……….. now this can all be done in one go ……… and the software to use on a PC is most certainly PODIUM
Wikipedia says on this subject …..
The publish/subscribe model of podcasting is a version of push technology in that the information provider chooses which files to offer in a feed and the subscriber chooses among available feed channels. While the user is not "pulling" individual files from the Web, there is a strong "pull" aspect in that the receiver is free to subscribe to (or unsubscribe from) a vast array of channels.
Podcasting is now used in Public Services to inform and update staff and visitor to a variety of institutions;
In education a rapidly growing group is using it to inform and stimulate students and to give them the power to learn on the move as well as to encourage them to make their own podcasts …. This coupled with the power and responsibility that ownership brings
In entertainment podcasts are being used to captivate and amuse …. Most podcasts are free to subscribe to but it is in this area that fee paying has come in. Rickie Gervaise charges for his latest work ( after a taster start which was free) …. £3.95 for The Complete Third Season or each episode at 95p
News is a big podcast puller in the USA and our own BBC produce a video podcast at 6.45 each day ready to download to your MP3 player to view or listen to as you travel to work or school.
Obviously music was always going to be big here and the medium of podcasting allows just anyone to perform for an audience of their own choice or to syndicate their brand of music to their friends
On the way up is the advertising implications of podcasts and as this is a ‘push’ technology companies are working really hard to give things to persuade listeners to listen…. The problem, they have is that if you don’t want to be advertised to you can always ditch the feed
The next shot, so I understand is into health care with podcasts about healthy eating and exercise ….
What next I wonder ...?
