Considered one of the early and foundational milestones in electronics engineering and developed as an offshoot of telegraphic encoding (see previously here and here), the American Standard Code for Information Interchange (ASCII) was first published by the American Standards Association (ASA—presently organised as the American Nation Standards Institute, ANSI) on this day in 1963. Its application in linking networks of machines was formalised and demonstrated by 1969 (see also) and has been since elevated to an internet standard, undergoing multiple revisions from conception through 2017. Initially recognised for its ability to aid in sorting list, character order is called ASCIIbetical and the collating sequence of data puts numbers and punctuation before letters and upper carriage letters before their smaller versions. While ASCII is constrained to a character set of only one hundred twenty eight, it is rolled into the larger and more inclusive, international Unicode standard.
