Blog" and "wiki" were already dictionary words in 2004 when Adam Curry, a former show host on MTV, used his own celebrity and the underlying technologies of blogging to popularise yet another next big thing: "podcasting" (which provided him with a new nickname, "podfather").
2004年，当“博客”和“维基”都已成为字典词条之时，MTV的前节目主持亚当・卡里运用自身的名气以及博客的基础技术又引爆了另一股流行风潮：“播客广播”（而这又赋予了他一个新的绰号――“播客之父”）。
A "podcast" is a web feed of audio or video files placed on the Internet for anyone to subscribe to, and also the content of that feed. Podcasters' websites also may offer direct download of their files, but the subscription feed of automatically delivered new content is what distinguishes a podcast from a simple download or real-time streaming.
In a nutshell, a podcast is an audio file in MP3 format and delivered online via RSS feed (webfeed) subscriptions. Podcast subscribers can listen to the show athis or her own leisure, which is the main attraction of this medium. And unlike Internet radio, there is no schedule to follow. Podcasts can update as often as the author has time to make a recording. Some only update once a month or so, while others update daily and sometimes more often than that.
Vocabulary
The term "podcast" was derived from two words: iPod (an Apple MP3 player) and broadcast. This is attributed to the pioneers of podcasting who are iPod users. However, don't be deceived by this term, as you don't need an iPod to broadcast and/or listen to podcasts. Any computer audio software that supports MP3 (Windows Media Player, QuickTime, etc.) and any portable device that supports media download and playback may be used to listen to them.
"Podcasting" is the term used to refer to the act of making and broadcasting podcasts. People who make and broadcast shows through podcasting are known as "podcasters".
How They Work
You need a podcast client/receiver to subscribe to a podcast. When you're subscribed, your client will check for new shows automatically when you ask it to. Then, you just listen to the podcasts on a computer or portable device (MP3 player, PDA or cellphone) when and where you want to. It works as follows. A podcaster records something - anything from music to philosophical ramblings, professional news or random noises - into a computer with the aid of a microphone, then posts this audio file onto the internet. There, people can listen to it and, more importantly, subscribe to a "feed" from the same podcaster, so that all new audio files from that source are automatically pulled down as soon as they are published. Whenever listeners dock their iPods or other music players for charging, the feeds that have newly arrived on the computers are transferred to the portable devices. People can then listen in their cars, while jogging, or wherever and whenever they please.
It is not quite true, therefore, that podcasting is to audio as blogging is to text. Podcasting is about "time-shifting" (listening offline to something at a time of one's own choosing, as opposed to a broadcaster's), whereas reading blogs requires a live internet connection and a screen. More subtly, podcasts are different from blogs and wikis in that they cannot link directly to other podcasts. This makes podcasting a less social, and perhaps less revolutionary, medium.
Mass Appeal
Nonetheless, its rise has been nothing short of astonishing. Adam Curry's own podcast, The Daily Source Code, has several million listeners. Apple's iTunes, the software application and online music store that makes iPods work, currently lists 20,000 free podcasts and is adding them at a fast clip, all before podcasting's second birthday. Podcasting is even expanding from audio to video, although this trend is as yet so new that several names ("vodcasting", "vidcasting", "vlogging") are still vying for the honour.
For listeners, the appeal is threefold. First, they become their own programmers, mixing the music and talk feeds that they enjoy. This liberates commuters, say, from commercial radio stations that, in America especially, seem only ever to get dumber and duller. Second, podcasts liberate listeners from advertising, and thus put an end to the tedious and dangerous toggling between the car radio's pre-set buttons at 100km an hour. (However, some podcasters are experimenting with putting advertisements into their podcasts.) Above all, the time-shifting that podcasts make possible liberates people from having to sit in their parked cars to hear the end of a good programme.
For creative types, professional or amateur, the appeal of podcasting is much the same as that of other participatory media: it dramatically lowers the costs of producing content. All they need is a microphone, a computer and an internet connection, and many people already have those.
所谓“播客”，是指那种在互联网上放有音频或视频文件可供所有人订阅的网络信息源，另外也指代该信息源上的内容。播客者的网站可能还会提供其文件的直接下载，不过，将播客与简单的下载或实时流式传输区别开来的是其所有的那种会自动更新内容的订阅信息源。
简而言之，播客就是一种以MP3为格式、通过RSS 信息源（网络信息源）订阅来进行在线传输的音频文件。订阅播客者可以在其空闲时来收听节目，而这正是该传媒方式的主要亮点所在。而且，与互联网广播不同，是没有可遵循的时间表的。只要原创者有时间录，播客就可以更新。有的大概每月只更新一次，还有的每天都更新而且有时还更为频繁。
播客相关术语
“播客”这个词由两个词衍生而来：“iPod”（苹果公司的MP3播放器）和“broadcast”。这要归功于播客广播的开创者都是iPod玩家。然而，可不要被这个词给唬住了，因为你并非需要有iPod才能播送和/或收听播客。任何支持MP3的电脑音频软件（如“Windows Media Player”和“QuickTime”等）以及任何支持媒体下载和录音重放功能的便携设备都可以被用来收听播客。
“播客广播”一词用于指代播客的制作与播送行为。制作并通过播客广播来播放节目的人被称为是“播客者”。
如何玩转播客
你需要有一个客户端/接收器来订阅播客。在你订阅之后，你的客户端会按你的要求自动检索新的节目。然后，你就可以随时随地在电脑或便携设备（MP3播放、PDA或手机）上收听播客了。其工作原理如下：播客者借助麦克风在电脑里录制东西（任何东西皆可，从音乐到哲学漫谈、业界新闻或随意声响），然后将这个音频文件粘贴到互联网上。人们随之就可以在网上收听了，更重要的是，人们可以从同一播客者那里订阅信息源，这样一来，新的音频文件在源点处一经便可全部自动拷贝下来。每当听众将其iPod或其它音乐播放器放入座充进行连线充电时，新近传入电脑的信息源就会被转存到这些便携设备中。人们随后就可以在他们的汽车中，在慢跑时，或是随心所欲地在任何地点和时间来收听了。
因此，将播客广播与音频的关系比作博客与文本的关系并不是完全正确的。播客广播与“滞后收听”（在一个自主选择的时间而非播送者选择的时间来离线收听某些节目）相关，而阅读博客则需要有即时的网络连接和一个屏幕。说得再细一点儿，播客与博客和维基的区别在于它们无法直接插入链接，与其它播客相连。这就使播客广播成为了一种交互性更差、可能还更缺乏革命性的传媒方式。
播客的大众吸引力
尽管如此，它的崛起一直以来都是惊人的。亚当・卡里自己的播客――“每日源代码”，已经拥有了数百万听众。苹果公司的iTunes（维持iPod运转的应用软件和在线音乐商店）目前列出了20000个免费播客，而且数量还在猛增，所有这一切都是在播客广播出现不到两年的时间内发生的。更有甚者，播客广播正在从音频领域扩展到视频领域，不过由于这一趋势到目前为止还过于新潮，以至于仍有不少词语（“vodcasting”、“vidcasting”、“vlogging”）在争夺这一冠名殊荣。
对于听众来讲，吸引力有三个方面。首先，他们成为了自己的专属节目编导，将自己喜爱的音乐和谈话信息源融合到了一起。这就使上班族等群体从那些似乎是越办越差、越办越没劲的商业电台（尤其是美国的电台）中解放了出来。其次，播客将听众从广告中解放了出来，因而就不会再出现那种在时速100公里时既枯燥又危险地来回调换车载收音机预置键的行为了。（然而，有些播客者却正试着将广告插入到他们的播客之中。）最重要的是，播客所成全的那种滞后收听手段使人们在收听好节目时得到了解放，不必为了一气听完而在停好车后还坐在车中。
对于有创造力的那类群体来讲，无论是专业人士还是业余爱好者，播客广播的吸引力与其它参与式媒体都相差无几：大大降低了内容制作的成本。他们所需要的就是一个麦克风、一台电脑和一个网络连接，而许多人都已拥有了这些东西。
