Pepsi is a soft drink made by Pepsico. It’s a refreshing and invigorating carbonated cola drink, popular worldwide. Throughout its history, Pepsi and Coca Cola have been rivals but if you ask many Pepsi fans they believe that Pepsi tastes better than Coke, They claim that it’s less sweet, less fizzy and has a different aftertaste. The ingredients differ as well. In 1975 Pepsico launched the Pepsi Challenge taste test. Originally, they went around public places and had blind tasting competitions to help promote and market Pepsi as its own drink. The Pepsi Challenge evolved into a challenge where you can even win prizes, for example the Pepsi Challenge during 2011 American X-Factor.
