Why are archdeacons (Anglican, Catholic, or Orthodox) called "The Venerable"? What is the origin, in Latin and English, of this title?

Wikipedia doesn't seem to provide a fleshed-out etymology of this title. Who first held it? When did its usage become applied to all archdeacons. And do archdeacons ever have issues with the title, which doesn't necessarily indicate their priestly/diaconal status?
