The Discovery Channel's "How it's Made" featured a segment on how road signs are manufactured, following a French company as it produces a stop sign. The introduction to the segment touches on the history of directional signage, including the government regulation of sign design, before exploring the silk screening of the fabric and cutting and curing of the steel.
