A podcast or netcast is a digital
medium consisting of
an episodic series of audio, video, PDF,or ePub files subscribed to and downloaded through web
syndication or
streamed online to a computer or mobile device. The word is a neologism and portmanteau derived from "broadcast" and
"pod" from the success of the iPod, as audio podcasts
are often listened to on players.
A list of all the audio or video files associated with a given series is
maintained centrally on the distributor's server as a web feed,
and the listener or viewer employs special client application
software, known as a podcatcher,
that can access this web feed, check it for updates, and download any new files
in the series. This process can be automated so that new files are downloaded
automatically, which may seem to the user as if the content is being broadcast
or "pushed" to them. Files are stored locally on the user's computer or other device ready for offline use, giving simple and convenient
access to the content. Podcasting contrasts with web casting (Internet streaming), which generally isn't
designed for offline listening to user-selected content. As discussed by
Richard Berry, pod casting is both a converged medium bringing together audio,
the web and portable media player, and a disruptive
technology that has caused some in the radio business to reconsider some of the
established practices and preconceptions about audiences, consumption,
production and distribution. This idea of disruptiveness is largely because no
one person owns the technology; it is free to listen and create content, which departs
from the traditional model of 'gate-kept' media and production tools. It is very much a horizontal media
form: producers are consumers and consumers become producers and engage in
conversations with each other. Thecterm "podcasting" was first
mentioned by Ben Hammersley in The Guardian newspaper in a February 2004 article,
along with other proposed names for the new medium. It is aportmanteau of the words "pod" —from iPod and "broadcast”.
Despite the etymology, the content can be accessed using any computer that can
play media files and not just portable music players. Use of the term
"podcast" predates the addition of native support for podcasting to
the iPod, or to Apple's iTunes software. Faced with the increasing
variety of devices able to consume the medium, the generic term netcasting was created, Both terms are completely synonymous.
Many people and groups including Dawn and Drew of The Dawn and Drew Show, Kris and Betsy
Smith of Croncast and Dan Klass of The Bitterest Pill contributed to
the early emergence and popularity of podcasts. Former MTV VJ Adam Curry in collaboration with Dave Winer, a
developer of RSS feeds, is credited
with coming up with the idea to automate the delivery and syncing of textual
content to portable audio players. The first application to make this process
feasible was iPodderX, developed by August Trometer and Ray Slakinski. Since
the 1930s there have been radio talk shows and news programs. By 2007, through
the evolution of the Internet capabilities, along with cheaper hardware and
software, audio podcasts were doing what was historically done through radio
broadcast stations.In
June 2005, Apple released iTunes 4.9 with native
support for podcasts. While this made receiving podcasts more convenient, it
effectively ended advancement of the podcast medium by independent developers.
To add to the cooling factor, Apple issued Cease and
Desist orders to many
podcast application developers and service providers for using the term
"iPod" or "Pod" in the name of their product. February 10,
2005, Shae Spencer Management LLC of Fairport, New York filed a trademark application to
register the term "podcast" for an "online prerecorded radio program
over the internet". On September 9, 2005, the United States Patent and Trademark
Office rejected the
application, citing Wikipedia's podcast entry as describing the history of the
term. The company amended their application in March 2006, but the USPTO
rejected the amended application as not sufficiently differentiated from the
original. In November 2006, the application was marked as abandoned.As of September 20, 2005, known trademarks that
attempted to capitalize on podcast include:GodCast, Podcast Realty, GuidePod,
Pod-Casting, MyPod, Podvertiser, Podango, ePodcast, PodCabin, Podcaster,
PodcastPeople, PodShop, PodKitchen, Podgram and Podcast. By February 2007,
there had been 24 attempts to register trademarks containing the word
"PODCAST" in United States, but only "PODCAST READY" from Podcast Ready, Inc. was approved. On September 26, 2004, it was reported that Apple started to crack down on businesses using the string
"POD", in product and company names. Apple sent a cease and desist letter that week to Podcast Ready, Inc., which markets an
application known as "myPodder". Lawyers for Apple contended that the
term "pod" has been used by the public to refer to Apple's music
player so extensively that it falls under Apple's trademark cover. It was
speculated that such activity was part of a bigger campaign for Apple to expand
the scope of its existing iPod trademark, which included trademarking "IPODCAST",
"IPOD", and "POD".[19] On November 16, 2006, the Apple Trademark Department stated
that Apple does not object to third party usage of "the generic term"
"podcast" to refer to podcasting services and that Apple does not
license the term. However, no statement was made whether Apple believes they
hold rights to itPersonal Audio, a
company referred to as a "patent troll" by the Electronic
Frontier Foundation, filed a patent on podcasting in 2009 for
a claimed invention in 1996. In February 2013, Personal Audio started suing
high-profile podcasters for royalties, including the Adam
Carolla Show and the How Stuff Works podcast. US Congressman Peter
DeFazio's previously proposed "SHIELD Act" intends to curb patent
trolls.ince
the spread of the Internet and the use of Internet broadband
connection TCP, which helps to identify different applications, a faster
connection to the Internet has been created and a wide amount of communication
has been created. Video podcasts have become extremely popular online and are
short clips of video, usually part of a longer recording. Video clips are being
used on pre-established websites and more and more websites are being created
solely for the purpose of video clips and podcasts. Video podcasts are being
streamed on intranets and extranets, private and public networks, and taking
communication through the Internet to whole new levels. Most video clips are
now submitted and produced by individuals and are becoming more common. Video
podcasts are also being used for web television, commonly referred to as Web
TV, which is a rapidly growing genre of digital entertainment, using various
forms of new media to deliver original shows or series to an audience.
Delivered originally online via broadband and mobile networks, web television
shows, or web series. Video podcasts used for web television are typically
short-form, anywhere from 2–9 minutes per episode. Typically they are used for
advertising, video blogs, amateur filming, journalism and convergence with
traditional media. An enhanced podcast can display images simultaneously with
audio. These can contain chapter markers, hyperlinks, and
artwork; all of which is synced to a specific program or device. When an
enhanced podcast is played within its specific program or device, all the
appropriate information should be displayed at the same time and in the same
window, making it easier to display materials. A podcast
novel (also known as a serialized audio book or podcast
audiobook) is a literary format that combines the concepts of a
podcast and an audiobook.
Like a traditional novel, a podcast novel is
a work of long literary fiction; however, this form of novel is recorded into
episodes that are delivered online over a period of time and in the end
available as a complete work for download. The episodes may be delivered
automatically via RSS, through a web site,
blog, or other syndication method. These files are either listened to directly
on a user's computer or loaded onto a portable media device to be listened to
later. The types of novels that are podcasted vary from new works from new
authors that have never been printed,
to well established authors that have been around for years to
classic works of literature that have been in print for over a century. In the
same style as an audiobook,
podcast novels may be elaborately narrated with separate voice actors for each
character and sound effects, similar to a radio play.
Other podcast novels have a single narrator reading the text of the story with
little or no sound effects. Podcast novels are distributed over the Internet,
commonly on a weblog. Podcast
novels are released in episodes on a regular schedule (e.g. once a week) or
irregularly as each episode is released when completed, and can either be
downloaded manually from a website or blog, be delivered automatically via RSS, or other method of
syndication. Ultimately, a serialized podcast novel becomes a completed audiobook. Podcast novelists use
giving away a free podcast version of their book as a form of promotion. Some
novelists have even secured publishing contracts to have their novels printed.
Podcast novelists have commented that podcasting their novels lets them build
audiences even if they cannot get a publisher to buy their books. These
audiences then make it easier to secure a printing deal with a publisher at a
later date. These podcast novelists also claim the exposure that releasing a
free podcast gains them makes up for the fact that they are giving away their
work for free.
