mp3 player

A portable media player (PMP) (also including the related digital audio player (DAP)) is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files. The data is typically stored on a compact disc (CD), Digital Video Disc (DVD), Blu-ray Disc (BD), flash memory, microdrive, or hard drive; most earlier PMPs used physical media, but modern players mostly use flash memory. In contrast, analogue portable audio players play music from non-digital media that use analogue media, such as cassette tapes or vinyl records.
Digital audio players (DAP) were often marketed as MP3 players even if they also supported other file formats and media types. The PMP term was introduced later for devices that had additional capabilities such as video playback. Generally speaking, they are portable, employing internal or replaceable batteries, equipped with a 3.5 mm headphone jack which can be used for headphones or to connect to a boombox, shelf stereo system, or connect to car audio and home stereos wired or via a wireless connection such as Bluetooth. Some players also include radio tuners, voice recording and other features.
DAPs appeared in the late 1990s following the creation of the MP3 codec in Germany. MP3-playing devices were mostly pioneered by South Korean startups, who by 2002 would control the majority of global sales. However the industry would eventually be defined by the popular Apple iPod. In 2006, 20% of Americans owned a PMP, a figure strongly driven by the young; more than half (54%) of American teens owned one, as did 30% of young adults aged 18 to 34. In 2007, 210 million PMPs were sold worldwide, worth US$19.5 billion. In 2008 video-enabled players would overtake audio-only players. Increasing sales of smartphones and tablet computers have led to a decline in sales of PMPs, leading to most devices being phased out, such as the iPod Touch on May 10, 2022, though certain flagship devices like the Sony Walkman are still in production. Portable DVD and BD players are still manufactured.
