History of SNOMED CT
SNOMED CT was a joint development between the NHS in England and the College of American Pathologists (CAP). It was formed in 1999 by the convergence of SNOMED RT and the United Kingdom's Clinical Terms Version 3 (formerly known as the Read Codes).
SNOMED itself was started in 1965 as SNOP (Systematized Nomenclature of Pathology), and later extended into other medical fields.
In 2007, the SNOMED CT intellectual property rights were transferred from the CAP to the SNOMED SDOŽ in the formal creation of the IHTSDO.
