BattleCreek, MI based
Kellogg Co, the makers of many
breakfast cereals (
Frosted Flakes,
Special K,
Froot Loops,
Corn Pops,
etc), and the
college staple of
choice (next to
macaroni and cheese),
Pop-Tarts. They were
IPO'd on 5/12/1959 (thank you nyse.com), which makes sure that they are here to stay.
