Kellogg's
Ah, Kellogg’s. Which of us hasn’t heard of them? A brand of instant recognition with numerous well known catchphrases (“They’re Grrreat!” and “Snap, Crackle & Pop” to name but two). Not much we can say that you don’t know already. But that isn’t going to stop us from trying.
Headquartered in Michigan, USA (although their largest factory is actually in Trafford, Manchester). Formed by brothers John and William, they invented corn flakes in a bid to improve the vegetarian diet of the inmates at Battle Creek Sanitarium, where they both worked. The brothers fell out, William got John to relinquish any rights to their exciting new foodstuff, and there you go. Bet you THAT kept John awake at night, but hindsight is a glorious thing.
