Podcast in the context of "Talk show"

A digital music store is a business that sells digital audio files of music recordings over the Internet. Customers gain ownership of a license to use the files, in contrast to a music streaming service, where they listen to recordings without gaining ownership. Customers pay either for each recording or on a subscription basis. Online music stores generally also offer partial streaming previews of songs, with some songs even available for full length listening. They typically show a picture of the album art or of the performer or band for each song. Some online music stores also sell recorded speech files, such as podcasts, and video files of movies.

In computing, a news aggregator, also termed a feed aggregator, content aggregator, feed reader, news reader, or simply an aggregator, is client software or a web application that aggregates digital content such as online newspapers, blogs, podcasts, and video blogs (vlogs) in one location for easy viewing. The updates distributed may include journal tables of contents, podcasts, videos, and news items.

Contemporary news aggregators include MSN, Yahoo! News, Feedly, Inoreader, and Mozilla Thunderbird.

AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands.

The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received much of the programming previously carried by radio. Later, AM radio's audiences declined greatly due to competition from FM (frequency modulation) radio, Digital Audio Broadcasting (DAB), satellite radio, HD (digital) radio, Internet radio, music streaming services, and podcasting.

Mobile television is television watched on a small handheld or mobile device, typically developed for that purpose. It includes services delivered via mobile phone networks, received free-to-air via terrestrial television stations, or via satellite broadcast. Regular broadcast standards or special mobile TV transmission formats can be used. Additional features include downloading TV programs and podcasts from the Internet and storing programming for later viewing.

According to the Harvard Business Review, the growing adoption of smartphones allowed users to watch as much mobile video in three days of the 2010 Winter Olympics as they watched throughout the entire 2008 Summer Olympics, a five-fold increase. However, except in South Korea, consumer acceptance of broadcast mobile TV has been limited due to a lack of compatible devices.

Music streaming services are a type of online streaming media service that focuses primarily on music, and sometimes other forms of digital audio content such as podcasts. These services are usually subscription-based services allowing users to stream digital copyright restricted songs on-demand from a centralized library provided by the service. Some services may offer free tiers with limitations, such as advertising and limits on use. They typically incorporate a recommendation system to help users discover other songs they may enjoy based on their listening history and other factors, as well as the ability to create and share public playlists with other users.

Streaming services saw a significant pace of growth during the 2010s, overtaking online music stores as the largest source of revenue to the United States music industry in 2015, and accounting for a majority since 2016. As a result of their ascendance, streaming services (as well as music-oriented content on video sharing platforms) were incorporated into the methodologies of major record charts; the "album-equivalent unit" was developed as an alternative metric for the consumption of albums, to account for digital music and streaming.

RSS (RDF Site Summary or Really Simple Syndication) is a web feed that allows users and applications to access updates to websites in a standardized, computer-readable format. Subscribing to RSS feeds can allow a user to keep track of many different websites in a single news aggregator, which constantly monitors sites for new content, removing the need for the user to manually check them. News aggregators (or "RSS readers") can be built into a browser, installed on a desktop computer, or installed on a mobile device.

Websites usually use RSS feeds to publish frequently updated information, such as blog entries, news headlines, episodes of audio and video series, or for distributing podcasts. An RSS document (called "feed", "web feed", or "channel") includes full or summarized text and metadata like publishing date and author's name. RSS formats are specified using a generic XML file.

In broadcasting, time shifting is the recording of programming to a storage medium to be viewed or listened to after the live broadcasting. Typically, this refers to TV programming but it can also refer to radio shows via podcasts.

In recent years, the advent of the digital video recorder (DVR) has made time shifting easier, by using an electronic program guide (EPG) and recording shows onto a hard disk. Some DVRs have other possible time-shifting methods, such as being able to start watching the recorded show from the beginning even if the recording is not yet complete. In the past, time shifting was done with a video cassette recorder (VCR) and its timer function, in which the VCR tunes into the appropriate station and records the show onto video tape.

Science journalism conveys reporting about science to the public. The field typically involves interactions between scientists, journalists and the public. There are many different examples of science writing. A few examples include feature writing, risk communication, blogs, science books, scientific journals, science podcasts and science magazines.
