IIRC, it was chosen because around that time a number of technological changes were introduced or popularized that represented a significant departure from previous years; e.g. non-ferrous frames, new joining techniques (TIG welding, epoxy bonding), non-standard tubing diameters, indexed shifting that actually worked, clipless pedals, etc.
