Podcast

A podcast is a program made available as a digital file for download over the Internet. It is an audio format, a mix of the words "iPod" and "broadcast", and the term was created in 2004. Podcasts are usually a series of digital audio files that people can download to listen to whenever they like. In the mid-2020s, video podcasts also became popular, with many people watching them on YouTube.

A podcast often has one or more hosts talking about a specific topic or current event. The discussion can be very planned or completely spontaneous. Podcasts combine creative sound with topics that range from science to everyday stories. Many podcasts have websites with extra information, like links, guest details, and places to talk about the show with others.

Podcasts are usually free to download, though some have ads or are supported by companies. Others might need a subscription or sell products. Because they are often free, podcasts are seen as a new way of sharing information.

Podcasting means making and sharing audio or video files using special web tools called RSS feeds. Podcasters use services like SoundCloud or Libsyn to help share their shows. These files then appear on places like Apple, Spotify, and YouTube, where people can listen or watch on their smartphones, music players, or smart televisions.

Etymology

"Podcast" is a mix of the words "iPod" and "broadcast". The word was first used by Ben Hammersley, a writer for The Guardian, in February 2004. Later, in September 2004, someone named Danny Gregoire used the word in a message to a group of people interested in digital audio. Even though the name includes "iPod", you can listen to podcasts on any device that can play audio files. The word was created before Apple added podcast features to the iPod and iTunes software.

Production and listening

A podcast generator keeps a list of files on a server as a web feed that you can find on the Internet. You use special software, called a podcast client, on a computer or music player to access this feed, check for updates, and download new episodes. This can happen automatically.

There are many mobile apps that let you follow and enjoy podcasts. These apps usually let you download shows or listen to them when you want. Most let you move around within the show and change how fast it plays. Many people listen to podcasts while traveling.

Podcasts mix together audio, the web, and portable music players, making them a new kind of medium. They’ve also changed how some radio stations think about their audience and how they make and share shows. The New York Times said that podcasts have become a popular way for famous people to share their projects.

Making a podcast doesn’t cost much, and they are often free to listen to. Podcasters can still make money by letting companies buy time for ads. They can also get help from listeners through crowdfunding websites like Patreon.

Types of podcasts

Podcasts come in many different styles and topics. Some are just audio, while others include video or images. One type is a video podcast, which adds video to the audio, like a web television show. Another type is an enhanced podcast, which mixes audio with images shown in a slide show.

There are also fiction podcasts that tell made-up stories, much like old radio dramas. Some podcasts turn novels into episodes, releasing one part at a time online.

Production technology

Podcast episodes are often saved in the mp3 digital audio format and put on dedicated or shared webserver space. Information about each episode and the podcast is shared using RSS feeds, which are XML-formatted files.

The simplest tools for a podcast are a computer and a microphone. It helps to have a sound-proof room and headphones. The computer needs a program for recording or streaming. Most microphones connect using USB. If more than one person is on the podcast, each person needs a microphone, and a USB audio interface is needed to combine their audio. If the podcast includes video, a separate webcam and extra lighting might be needed.
