The cereal market is a profitable one. According to the 2008 Pell research, American breakfast cereal sales were more than $13 billion that year. Cereal has a long history. Kellogg’s Corn Flakes, for example, have been around since 1906. Prizes inside cereal boxes or connected to cereals have been around for almost as long. Cereal began as a health food, and later, sweetened cereals were introduced. The sugary cereals were soon marketed to children with Trix Rabbit and Tony the Tiger, which are still used decades after they debuted. The images were updated over the years. Attempts to regulate the images used in cereals aimed at children have failed.
