Kellogg's Frosted Flakes is a breakfast cereal, produced by the Kellogg Company and consisting of sugar-coated corn flakes. It was introduced in the United States in 1951, as Sugar Frosted Flakes. The word 'sugar' was dropped from the name in the 1980s. 'Frosted Flakes', by itself, is purely a description of the product. As a result, that term cannot be trademarked and can be used by any company for a similar product. On packaging, the words 'of corn' are added below the Frosted Flakes logo. 'Kellogg's Frosted Flakes' and 'Frosties' are registered trademarks in their respective markets. Tony the Tiger has been the mascot of Frosted Flakes since its introduction. Tony is known for uttering the cereal's slogan: 'They're Gr-r-reat!' (pronounced as one elongated word, not a stutter). Tony the Tiger was originally voiced internationally by Thurl Ravenscroft, until his death in 2005.
