Hydrox is the original sandwich cookie introduced in 1908. It thrived until 1912, when Nabisco launched Oreo. With Nabisco's superior distribution and advertising, Hydrox was soon outmatched. By 1998, Hydrox sales totaled $16 million, while Oreo's revenues were at $374 million. Hydrox has been purchased by Keebler, whose elves are trying to give the cookie a major facelift.
