A Special Daughter

Special K is an American brand of breakfast cereal introduced to the United States in 1955 by one of their food kitchen researchers, Jimmy Harris. As the father of seven boys, he was pleasantly surprised by the birth of one daughter, Kathleen. He called her his "Special K." Since "K" was the first letter in the Kellogg's logo, the company allowed him to use the name for the new cereal. The general public might think the "K" simply stands for the special cereal from Kellogg's. 

The Original Oreo

Hydrox is a cream-filled chocolate sandwich cookie that debuted in the United States in 1908 and was manufactured by Sunshine Biscuits for over ninety years. Hydrox was largely discontinued in 1999, three years after Sunshine was acquired by Keebler, which was later acquired by Kellogg. In September 2015, the product was reintroduced by Leaf Brands.

The Oreo brand was created in 1912. It offered more creme filling, a sweeter imitation of Hydrox, and eventually surpassed Hydrox in popularity. It resulted in the Hydrox cookies being perceived by many as an Oreo off-brand. The Hydrox name sounds eerily like it is chemically manufactured compared to the cute-sounding Oreo name.
