History
The original PICMG mission was to provide extensions to the PCI standard developed by PCI-SIG for a range of applications. The organization's collaborations eventually expanded to include a variety of interconnect technologies for industrial computing and telecommunications. PICMG's specifications are used in a wide variety of industries including industrial automation, military, aerospace, telecommunications, medical, gaming, transportation, physics/research, test and measurement, energy, drone/robotics, and general embedded computing.
In 2011, PICMG completed its transfer of assets from the Communications Platforms Trade Association (CP-TA). Since 2006, CP-TA had been a collaboration of communications vendors, developing

The Linux Foundation, and the
Service Availability Forum. PICMG has continued the educational and marketing outreach formerly conducted by members of the CP-TA marketing work group.
Specification naming convention
For many years, PICMG used a numerical naming convention with specification being referred to as “PICMG X.YY”. Where X was used to denote differing form factors ("1" for
slot card based single board computers, "2" for
CompactPCI, and "3" for
AdvancedTCA) while YY was used to indicate incremental changes, option definitions, or a slight variation of a specification form its core specification. In 2003, PICMG added an acronym-based naming convention for its specifications to yield better results from internet search engines. Specifications are now often named ABCD.X where ABCD is an acronym of the specification. In this naming convention, base or main specifications are denoted with X=0 (i.e. ABCD.0), and PICMG subsidiary specifications are denoted X>0. PICMG subsidiary specifications represent how various options or variations of a based specification should be handled.
