===Open Font Format===
Adobe and Microsoft continued to develop and refine OpenType over the next decade. Then, in late 2005, OpenType began migrating to an open standard under the [[International Organization for Standardization]] (ISO) within the [[MPEG]] group, which had previously (in 2003) adopted OpenType 1.4 by reference for [[MPEG-4]].<ref name="OFF-chiariglione">{{cite web |url=http://mpeg.chiariglione.org/technologies/mpeg-4/mp04-off/index.htm |title=ISO/IEC 14496-22 "Open Font Format" |author=ISO/IEC JTC 1/SC 29/WG 11 |publisher=chiariglione.org |archive-url=https://web.archive.org/web/20100430175925/http://mpeg.chiariglione.org/technologies/mpeg-4/mp04-off/index.htm |date=July 2008 |archive-date=2010-04-30 |access-date=2020-02-21}}</ref><ref>{{cite web|url=https://www.adobe.com/aboutadobe/pressroom/pressreleases/200508/081505OpenTypeISO.html |title=ISO To Adopt OpenType File Format as Font Standard For MPEG-4 |publisher=Adobe Systems Incorporated |date=2005-08-15 |access-date=2010-01-28 |url-status=dead |archive-url=https://web.archive.org/web/20110605091909/http://www.adobe.com/aboutadobe/pressroom/pressreleases/200508/081505OpenTypeISO.html |archive-date=2011-06-05 }}</ref><ref>{{cite web|url=http://kikaku.itscj.ipsj.or.jp/sc29/open/29view/29n55201.doc |title=Referencing Explanatory Report to accompany FPDAM/FDAM Submission of ISO/IEC 14496–11/Amd.2, Referenced Specification: The OpenType font format specification, version 1.4. |date=July 2003 |format=DOC |access-date=2010-01-28  |url-status=dead |archive-url=https://web.archive.org/web/20140512223957/http://kikaku.itscj.ipsj.or.jp/sc29/open/29view/29n55201.doc |archive-date=2014-05-12 }}</ref><ref>{{cite web|url=http://kikaku.itscj.ipsj.or.jp/sc29/open/29view/29n6929t.doc |title=Combined CD Registration and CD Consideration Ballot on ISO/IEC CD 14496-22: Information technology – Coding of audio-visual objects – Part 22: Open Font Format – SC 29/WG 11 N 7485 |date=2005-09-01 |format=DOC |access-date=2010-01-28  |url-status=dead |archive-url=https://web.archive.org/web/20140512223958/http://kikaku.itscj.ipsj.or.jp/sc29/open/29view/29n6929t.doc |archive-date=2014-05-12 }}</ref> Adoption of the new standard reached formal approval in March 2007 as ISO Standard [[ISO/IEC]] 14496-22 (MPEG-4 Part 22) called '''Open Font Format''' (OFF, not to be confused with [[Web Open Font Format]]),<ref>{{cite web|url=http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=43466 |title=ISO/IEC 14496-22:2007 – Information technology – Coding of audio-visual objects – Part 22: Open Font Format |publisher=ISO |date=2009-07-31 |access-date=2009-11-11}}</ref> sometimes referred to as "Open Font Format Specification" (OFFS).<ref name="OFF-chiariglione" /> The initial standard was technically equivalent to OpenType 1.4 specification, with appropriate language changes for ISO.<ref>{{cite web |url=http://standards.iso.org/ittf/PubliclyAvailableStandards/c043466_ISO_IEC_14496-22_2007(E).zip |title=ISO/IEC 14496-22, First edition 2007-03-15, Information technology — Coding of audio-visual objects — Part 22: Open Font Format |format=ZIP |date=2007-03-15 |author=ISO |access-date=2010-01-28}}</ref> The second edition of the OFF was published in 2009 (ISO/IEC 14496-22:2009) and was declared "technically equivalent" to the "OpenType font format specification".<ref name="ISO-2nd-edition">{{cite web |url=http://www.iso.org/iso/iso_catalogue/catalogue_ics/catalogue_detail_ics.htm?csnumber=52136 |title=ISO/IEC 14496-22:2009 – Information technology – Coding of audio-visual objects – Part 22: Open Font Format |publisher=ISO |date=2009-07-31 |access-date=2010-01-28}}</ref><ref>{{cite web |url=http://standards.iso.org/ittf/PubliclyAvailableStandards/c052136_ISO_IEC_14496-22_2009(E).zip |title=ISO/IEC 14496-22, Second edition 2009-08-15, Information technology — Coding of audio-visual objects — Part 22: Open Font Format |format=ZIP |date=2009-08-15 |author=ISO |access-date=2010-01-28}}</ref> Since then, OFF and OpenType specifications have been maintained in sync.

By 2001 hundreds of OpenType fonts were on the market. Adobe finished converting their entire font library to OpenType toward the end of 2002. {{As of|2005|alt=As of early 2005}}, around 10,000 OpenType fonts had become available, with the Adobe library comprising about a third of the total. By 2006, every major [[Type foundry|font foundry]] and many minor ones were developing fonts in OpenType format.{{Citation needed|date=July 2011|reason=uncited statistics}}
