I Can't Believe It's Not Butter! is a brand of margarine,[2][3] produced by Flora Food Group[4] and marketed as a substitute for butter.[2]
History
The J.H. Filbert company, based in Baltimore, Maryland, US developed the product in 1979 as a low-cost alternative to butter for the food service industry.[5] The name originated from a comment by the husband of a company secretary as he sampled the product and it was first marketed to retail consumers in 1981.[1]
