They are three elves who first appeared in the 1930s.
In the early 1950s, there was a fourth elf named Pow, but he was later dropped.
In the early 1990s, Snap, Crackle and Pop were portrayed as superheroes.
In the late 1990s to early 2000s, they were stop-motion instead of their usual hand drawn animation. They were later CGI animated.
