Indigital electronics,analogue electronics andentertainment, theuser interface may includemedia controls,transport controls orplayer controls, to enact and change or adjust the process ofvideo playback,audio playback, and alike. These controls are commonly depicted as widely known symbols found in a multitude of products, exemplifying what is known asdominant design.
Media control symbols are commonly found on both software and physical media players,remote controls, andmultimedia keyboards. Their application is described in ISO/IEC 18035.[1]
The main symbols date back to the 1960s, with the Pause symbol having reportedly been invented atAmpex during that decade for use onreel-to-reel audio recorder controls, due to the difficulty of translating the word "pause" into some languages used in foreign markets. The Pause symbol was designed as a combination of the existing square Stop symbol and thecaesura, and was intended to evoke the concept of an interruption or "stutter stop".[2][3] The right-pointing triangle was adopted to indicate the direction of tape movement during playback. This design choice was straightforward: the arrow pointed in the direction the tape advanced. Over time, this symbol became standardized across various media devices, from cassette players to CD players, and eventually digital interfaces.

The Play symbol is arguably the most widely used of the media control symbols. In many ways, this symbol has become synonymous with music culture and more broadly the digital download era. As such, there are now a multitude of items such as T-shirts, posters, and tattoos that feature this symbol.[citation needed] Similar cultural references can be observed with thePower symbol which is especially popular among video gamers and technology enthusiasts.
Media symbols can be found on an array of advertisements: from live music venues to streaming services.
In 2012, Google rebranded its digital download store toGoogle Play,[7] using the Play symbol in its logo. The Play symbol also serves as a logo forYouTube since 2017.[8]Television station ownersMorgan Murphy Media andTEGNA have begun to institute the Play symbol into the logos of their stations to further connect their websites to their over-the-air television presences.
Since the 2000s, there has been a proliferation of electronics that use media control symbols in order to represent the Run, Stop, and Pause functions. Likewise, user interface programing pertaining to these functions has also been influenced by that of media players.[citation needed]
For example, some washers and dryers with an illuminated Play/pause button are programmed such that it stays lit when the appliance is running. A line ofPhilips pasta makers has the Play/pause button for controlling the pasta-making process.[9]
