What is PodCasting?
is a web-based broadcast medium in which
media files are made available online thus
allowing software to automatically detect
and download new files (generally via RSS).
A PodCast is comparable to an audio magazine
subscription in that the subscriber receives
regular programs that he/she can listen to
or view at his/her own leisure. It can also
be considered as the internet equivalent of
timeshift-capable digital video recorders
(DVRs) such as TiVo, which allows users to
automatically record and store television
programs for later viewing.
most often involves audio files in MP3
format but different formats and other types
of files, such as video, can also be
is capable of handling
both audio and video recording, eliminating
the need to use separate programs to create
PodCasts. It also has the ability to create
and publish PodCasts to designated servers,
and create and maintain RSS feeds.
The word "
" is a merger of the
words iPod and broadcasting. The name
"PodCast" is no longer specifically related
to the iPod but to any software and hardware
combination that permits the downloading and
playing of files on any device that is
capable of playing modern audio and/or video
This technology enables anyone to
their own (internet based)
radio or television show, without requiring
expensive hardware. It is now easy to
create a show without the exorbitant costs
paid to broadcast companies to air the
program and where, more often then not, you
end up paying for airtime slots which have
very few listeners. PodCasts are
subscription based, which means that
listeners/viewers can select what they want
to hear or view. This system has already
proven successful as there are countless
popular internet programs
that draw in
listeners by the tens of thousands plus.
Established standard radio shows are also
reaching out with PodCasts of their own.
For example; Coast to Coast AM, a hugely
popular late-night talk-show program runs
PodCasts as a pre-paid subscription service.
Another popular talk-show, Rush Limbaugh,
also has a pre-paid subscription service.
The BBC and CBC
some of their
popular radio programs as well.
