In 1968, Lincoln Snacks developed a nut-free,
kosher sugar-glazed popcorn with a strong yellow color—as a variant of their other popcorn products,
Fiddle Faddle and
Poppycock. When Lincoln executives invited major ad agencies in Chicago to pitch ideas for a name and marketing concept, a small agency, Hurvis, Binzer & Churchill won the account, naming the product "Screaming Yellow Zonkers" and presenting it in a black box with bold graphics, detailed illustrations and funny text. The snack was introduced, first in the Midwest, on August 15, 1969. ==Discontinuation==
