The Yand Corporation was a business on the planet Ferenginar dating back to at least the 22nd century. Subliminal marketing experts for the Yand Corporation determined that the patterns of skimmerways imprinted themselves on the brains of skimmer drivers, a discovery that influenced the design of subsequent skimmerways. A primary example was Skimmerway Interchange 405 outside West Wormwood, designed to spell out an advertising slogan for Slug-o-Cola. (DS9 reference: Legends of the Ferengi)
