Trusted Platform Module (TPM) was conceived by a [[computer industry]] consortium called [[Trusted Computing Group]] (TCG). It evolved into ''TPM Main Specification Version 1.2'' which was standardized by [[International Organization for Standardization]] (ISO) and [[International Electrotechnical Commission]] (IEC) in 2009 as ISO/IEC 11889:2009.<ref>{{cite web |url=http://www.iso.org/iso/catalogue_detail.htm?csnumber=50970 |title=ISO/IEC 11889-1:2009 – Information technology – Trusted Platform Module – Part 1: Overview |website=ISO.org |publisher=[[International Organization for Standardization]] |date=May 2009 |access-date=November 30, 2013 |archive-date=January 28, 2017 |archive-url=https://web.archive.org/web/20170128033043/http://www.iso.org/iso/catalogue_detail.htm?csnumber=50970 |url-status=live }}</ref> ''TPM Main Specification Version 1.2'' was finalized on 3 March 2011 completing its revision.<ref>{{Cite web|title=TPM 1.2 Main Specification|url=https://trustedcomputinggroup.org/resource/tpm-main-specification/|access-date=2021-11-08|website=Trusted Computing Group|language=en-US}}</ref><ref name="TPM_Main_Specs">{{Cite web | url = https://www.trustedcomputinggroup.org/tpm-main-specification/ | title = Trusted Platform Module (TPM) Specifications | publisher = [[Trusted Computing Group]] | date = March 1, 2011 | access-date = October 30, 2016 | archive-date = October 22, 2017 | archive-url = https://web.archive.org/web/20171022063836/https://trustedcomputinggroup.org/tpm-main-specification/ | url-status = live }}</ref>

When a new revision is released it is divided into multiple parts by the Trusted Computing Group. Each part consists of a document that makes up the whole of the new TPM specification.
