The CD was planned to be the successor of the [[gramophone record]] for playing music, rather than primarily as a data storage medium, but from its origins as a format for music, its use has grown to encompass other applications. In 1983, following the CD's introduction, [[Kees Schouhamer Immink|Immink]] and [[Joseph Braat|Braat]] presented the first experiments with erasable compact discs during the 73rd [[Audio Engineering Society|AES]] Convention.<ref>{{cite journal|title=Experiments Toward an Erasable Compact Disc| journal=Journal of the Audio Engineering Society | date=August 1984 | volume=32 | issue=7/8 | pages=531–538 |url= http://www.aes.org/e-lib/browse.cfm?elib=4492|access-date=26 October 2014| last1=Immink | first1=Kees A. | last2=Braat | first2=Joseph J. }}</ref> In June 1985, the computer-readable [[CD-ROM]] (read-only memory) was introduced and, in 1990, the [[CD-R]]ecordable, also developed by both Sony and Philips.<ref name="AutoMR-10">The world's first CD-R was made by the Japanese firm [[Taiyo Yuden]] Co., Ltd. in 1988 as part of the joint Philips-Sony development effort.</ref> Recordable CDs were a new alternative to tape for recording music and copying music albums without the defects introduced in the compression used in other [[digital recording]] methods. Other newer video formats such as [[DVD]] and [[Blu-ray]] use the same physical geometry as CD, and most DVD and Blu-ray players are [[backward compatible]] with audio CD.

By the early 2000s, the CD player had largely replaced the [[audio cassette]] player as standard equipment in new automobiles, with 2010 being the final model year for any car in the US to have a factory-equipped cassette player.<ref name=nyt20120718>{{cite news|url=https://www.nytimes.com/2011/02/06/automobiles/06AUDIO.html|title=For Car Cassette Decks, Play Time Is Over|last=Williams|first=Stephen|newspaper=New York Times|date=4 February 2011|access-date=18 July 2012 }}</ref> Currently, with the increasing popularity of portable digital audio players, such as mobile phones, and solid state music storage, CD players are being phased out of automobiles in favor of minijack auxiliary inputs and connections to USB devices.{{citation needed|date=December 2015}}

Some CD players incorporate disc changers. Commonly these can hold 3, 5, 6, or 10 discs at once and change from one disc to the next without user intervention. Disc changers capable of holding up to 400 discs at once were available. Also, the user can manually choose the disc to be played, making it similar to a [[jukebox]]. They were often built into car audio and home stereo systems, although 7 disc CD changers were once made by [[NEC]] and [[Nakamichi]]<ref name="Nakamichi MBR-7 7 Disc CD ROM Changer">{{cite web |url=https://www.computinghistory.org.uk/det/49389/Nakamichi-MBR-7-7-Disc-CD-Rom-Changer/ |title=Nakamichi MBR-7 7 Disc CD-Rom Changer - Peripheral - Computing History |website=Computing History}}</ref> for PCs. Some could also play DVD and Blu-ray discs.

Meanwhile, with the advent and popularity of [[Digital distribution|Internet-based distribution]] of files in [[Lossy compression|lossily-compressed]] [[audio format]]s such as [[MP3]], sales of CDs began to decline in the 2000s. For example, between 2000 and 2008, despite overall growth in music sales and one anomalous year of increase, major-label CD sales declined overall by 20%<ref name="AutoMR-11">{{cite news |first= Ethan|last= Smith|title=Music Sales Decline for Seventh Time in Eight Years: Digital Downloads Can't Offset 20% Plunge in CD Sales |url=https://www.wsj.com/articles/SB123075988836646491?mod=rss_whats_news_technology&mg=com-wsj |newspaper=Wall Street Journal |date=2 January 2009 |access-date=4 March 2009 }}</ref> – although independent and DIY music sales may be tracking better (according to figures released 30 March 2009), and CDs still continue to sell greatly.<ref name="AutoMR-12">{{cite web |url=http://indiemusicstop.wordpress.com/2009/04/01/cd-baby-payouts-surge/ |title=CD Baby Payouts Surge |publisher=Indiemusicstop.wordpress.com |date=30 March 2009 |access-date=1 December 2009 |url-status=dead |archive-url=https://web.archive.org/web/20110718100639/http://indiemusicstop.wordpress.com/2009/04/01/cd-baby-payouts-surge/ |archive-date=18 July 2011 }}</ref> As of 2012, CDs and DVDs made up only 34 percent of music sales in the United States.<ref>{{cite web|url=http://www.tokyotimes.com/buying-cds-continues-to-be-a-tradition-in-japan/|title=Buying CDs continues to be a tradition in Japan - Tokyo Times|date=23 August 2013|access-date=21 January 2018|archive-date=20 December 2016|archive-url=https://web.archive.org/web/20161220150903/http://www.tokyotimes.com/buying-cds-continues-to-be-a-tradition-in-japan/|url-status=dead}}</ref> In Japan, however, over 80 percent of music was bought on CDs and other physical formats as of 2015.<ref>{{cite news|author=Sisaro, Ben|title=Music Streaming Service Aims at Japan, Where CD Is Still King|work=New York Times|date=11 June 2015|url=https://www.nytimes.com/2015/06/12/business/media/line-music-a-new-streaming-service-aims-at-japanese-market.html}}</ref> As of 2020, compact cassettes, vinyl records, and CDs are still being released by some musicians, primarily as merchandise, to allow fans to provide financial support while receiving something tangible in return.
