"I can’t believe it’s not Butter" was launched in the UK in 1991 by Unilever, having been around in the US since 1986.
Over the past twenty years, outstanding advertising - featuring the likes of the famous Spitting Image 'cow puppets' and Ozzy Osbourne - has played an important part in establishing "I can't believe it's not Butter" as the definitive impersonator of butter. Easy to spread from the fridge with an amazingly buttery taste and with half the saturated fat of butter, it is a convenient, delicious alternative to butter.
