HistoryThe design of TWAIN began in January 1991. The TWAIN group was originally launched in 1992 by several members of the imaging industry, with the intention of standardizing communication between image handling software and hardware.[1] Review of the original TWAIN Developer's Toolkit occurred from April, 1991 through January, 1992.[2] The word TWAIN is not officially an acronym, but it is a backronym. The official website notes that "the word TWAIN is from Kipling's "The Ballad of East and West" — '...and never the twain shall meet...' — reflecting the difficulty, at the time, of connecting scanners and personal computers. It was up-cased to TWAIN to make it more distinctive. This led people to believe it was an acronym,[3] and then to a contest to come up with an expansion. None was selected, but the entry Technology Without an Interesting Name continues to haunt the standard."[4][5] For example, the Encyclopedia of Information Technology lists "Technology Without an Interesting Name" as the official meaning of TWAIN.[6]
