Cheez-Its are the snack that's been around the longest, as these were invented in 1921. However, it's important to note that Kellogg's wasn't the brand behind the creation of this savory cracker.

Major League Soccer and Kellogg’s have announced a multi-year partnership extension which designates Cheez-It and Pringles as the league’s official snacks, and Eggo as the official waffle.

Further, without ties to the faster-growing snacks arm (which now sits inside narrow-moat Kellanova), WK Kellogg is left with a subpar scale, generating less than $3 billion in sales annually.
