Where does marbit come from?

Marbit, a blend of marshmallow and bit, began as an industry term and has been in use for over 30 years.

While cereals aimed at health-conscious adults are packed with whole grains and fiber, cereals for their children contain things called "marbits" (bits of marshmallows), malt syrup, corn syrup, brown sugar, honey and other sugar products.

How is marbit used?

Sparingly, for now. Although the word has been around for a while, marbit has seemingly yet to reach escape velocity into the broader consciousness, possibly because most people eating cereal in the morning aren’t thinking too deeply about its nomenclature.
