PMCP's development is managed by the ATSC's TSG/S1 group, which meets as needed, and reports to the Technology and Standards Group within the ATSC. It is an open, due process group, with a diverse membership, which during the heydey of PMCP development, numbered in the dozens.
PMCP was first published as A/76 in November 2004,<ref>http://www.atsc.org/news_informationcms/pressindex.php/2004communications/PR_PMCP_11_04.htmpress-releases/122-new-atsc-pmcp-standard-powers-psip</ref> and enjoys adoption from a variety of broadcast equipment and system vendors. Two revisions (largely backwards-compatible) with the standard have been made. ATSC A/76a extended PMCP to include metadata necessary for proper signaling of ACAP data broadcast elements, and A/76B, was released in 2007, fixed some errors and made the schema usable with the related SMPTE S2021 (BXF) schema.
