THRED

The story behind the word. Long before fiber-optic cables spanned the globe, 'thread' meant a fine line of twisted fiber drawn out from raw wool or flax. Nineteenth-century authors used 'thread' metaphorically to describe the narrative line of a complex story. When early computer bulletin boards were designed, programmers adopted the term for connected message chains, visualising individual replies as single strands forming a woven discussion.
