For much of its history, Vicks products were manufactured by the family-owned company Richardson-Vicks, Inc., based in Greensboro, North Carolina.

Procter & Gamble divested the Vicks VapoSteam U.S. liquid inhalant business and sold it to Helen of Troy in 2015.

Lunsford Richardson sent out millions of samples of Vicks VapoRub, "inadvertently" inventing the concept of junk mail, say North Carolina state historians.

The company archives (including related personal records of the Richardson family) from at least about 1920 or so, up to the 1985 sale to Procter & Gamble, are housed at the University of North Carolina at Chapel Hill.
