Kellogg's Sugar Frosted Flakes of Corn, better known simply as Frosted Flakes, is a breakfast cereal first introduced by the Kellogg Company. It consists of corn flakes "frosted" or coated with sugar. The "Frosted Flakes" name is used by Kellogg's in United States and Canada. The cereal was first introduced in 1952 as Sugar Frosted Flakes. The word "sugar" was dropped from the product in the 1980s during a time when many cereals dropped "sugar" from their titles.
"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 making a similar product. By contrast, "Kellogg's Frosted Flakes" and "Frosties" are registered trademarks in their respective markets.
- In 2003, Kellogg's launched Tony's Cinnamon Krunchers. The slogan was "They're Great 'Till They're Gone." This cereal was discontinued by Kellogg's in 2007 due to poor sales.
- In 2008, Kellogg's introduced Frosted Flakes Gold. It is flavored with honey and claims to provide longer lasting energy than original Frosted Flakes.
- In 2009, Kellogg's introduced Frosted Flakes Pink.
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!". Tony the Tiger was originally voiced by Thurl Ravenscroft, who continued until his death in 2005. The character is currently voiced in the USA by the former professional play-by-play announcer, Jim Van Horne, who also played Tony the Tiger in a television commercial in 1997. He can be seen wearing a red ascot on all frosted flakes cereal boxes. In the UK, Tony the Tiger also was voiced by his original voice artist Thurl Ravenscroft but after his death Tom Hill voiced Tony in the UK.
Another character, Katy the Kangaroo, was on the Frosted Flakes box for a short time.
The Frosties Kid was an Internet meme during the spring and summer of 2006, stemming from an advertisement aired on British and Irish television stations in spring 2006 in which the viewer is repeatedly told that "They're gonna taste great". Rumors in Internet blogs and Internet forums that the actor had committed suicide were soon noted by snopes.com when they investigated this meme. Questions about the Frosties Kid are still raised, with perhaps the most compelling rumor being that he is actually a CGI creation, a rumor which Snopes described as 'one of the more interesting theories', but never ruled out.
