Don't miss
The episode’s sharpest turn comes when the commercial rivalry gives way to federal convictions involving Cumberland executives.
The brief
Sweet’N Low’s fight to stay relevant begins inside Cumberland Packing, where a market challenge from Equal and Splenda coincides with an internal crisis.
Aspartame’s approval helped Equal overtake Sweet’N Low, while Monsanto prepared for patent expiration, falling prices, and the end of its monopoly.
Cumberland answered Equal’s celebrity advertising with mockery, but the campaign could not reverse the market’s shift toward the rival sweetener.
The business conflict darkens as Marvin Eisenstadt and Joe Asaro plead guilty to federal tax-related offenses and conspiracy against the Internal Revenue Service.
Later disputes over brain tumors, Splenda’s sugar branding, and sucralose’s alleged health effects show how scientific uncertainty becomes commercial ammunition.
