The protocols and specifications of the standard were developed by the Infrared Data Association (abbreviated IrDA, giving the name to the standard itself), an industry-driven interest group that was founded in 1994<ref name="founding">{{cite web|url=http://www.irda.org/displaycommon.cfm?an=1|title=About IrDA|archive-url=https://web.archive.org/web/20040610101333/http://www.irda.org/displaycommon.cfm?an=1|archive-date=2004-06-10}}</ref> by around 50 companies. 

IrDA was popular on PDAs, laptops and some desktops<ref>{{cite web|url=https://books.google.com/books?id=eOkoi_DOyhAC&dq=first+irda+infrared&pg=PA56 |title=PC Mag |date=3 April 2001}}</ref> from the late 1990s<ref>{{cite book|url=https://books.google.com/books?id=O4m0TrliwscC&dq=irda+infrared&pg=PA125 |title=Wireless Internet Applications and Architecture: Building Professional Wireless Applications Worldwide |isbn=9780201733549 |last1=Beaulieu |first1=Mark |year=2002}}</ref> through the early 2000s.<ref>{{cite web|url=https://www.zdnet.com/article/enterprise-pda-phones-reviewed/ |title=Enterprise PDA phones reviewed |website=[[ZDNet]]}}</ref><ref>{{cite web |title=HP iPAQ h6300 Pocket PC review: HP iPAQ h6300 Pocket PC |website=[[CNET]] |archive-url=https://web.archive.org/web/20230531170929/https://www.cnet.com/reviews/hp-ipaq-h6300-pocket-pc-review/ |archive-date=2023-05-31 |url-status=live |url=https://www.cnet.com/reviews/hp-ipaq-h6300-pocket-pc-review/}}</ref> However, it has been displaced by other wireless technologies such as [[Bluetooth]],<ref name=":0">{{cite book|url=https://books.google.com/books?id=a3_S-c8nfqsC&dq=irda+infrared&pg=PA62 |title=Wireless Networks for Dummies |isbn=9780764579776 |last1=Lewis |first1=Barry D. |last2=Davis |first2=Peter T. |date=27 October 2004}}</ref> and [[Wi-Fi]], favored because they don't need a direct line of sight and can therefore support hardware like mice and keyboards. It is still used in some environments where interference makes [[radio]]-based wireless technologies unusable.

An attempt was made to revive IrDA around 2005<ref>{{cite web|url=http://irdajp.info/irsimpleprdenhance.html |title=Irdajp.info}}</ref> with IrSimple protocols by providing sub-1-second transfers of pictures between cell phones, printers, and display devices. IrDA hardware was still less expensive and didn't share the same security problems encountered with wireless technologies such as Bluetooth. For example, some Pentax DSLRs (K-x, K-r) incorporated IrSimple for image transfer and gaming.<ref>http://www.pentaximaging.com/about-us.aspx?p=press&pid=PENTAXANNOUNCESK-rDIGITALSLRANDNEW35MMLENS20100908174223 {{Webarchive|url=https://web.archive.org/web/20110927143215/http://www.pentaximaging.com/about-us.aspx?p=press&pid=PENTAXANNOUNCESK-rDIGITALSLRANDNEW35MMLENS20100908174223 |date=2011-09-27}} Pentax K-r</ref>
