Step 1 : Introduction to the question "Which breakfast cereal is represented by the cartoon mascots "Snap, Crackle and Pop"?"
Rice Krispies cereal is widely known with a long advertising history, with the elf cartoon characters Snap, Crackle and Pop touting the brand. Snap! Crackle! and Pop!, the animated cartoon mascots for Rice Krispies, were created by illustrator Vernon Grant in the 1930s. The original gnome-like Snap! first appeared in 1933 on a package of Kellogg's Rice Krispies. Crackle! and Pop! came later, and since 1939, the three have been together in many forms of advertising, including radio, movie shorts, and comic strips. They are the first and longest-running cartoon characters to represent a Kellogg's product.
