logo.

A logo is a very powerful thing. It should emulate What the company is about, describe it in one simple image. A logo can make or break a company. Over the years companies change their logos for different reasons. Some become successful and others fall and roll into the large pile of already dying businesses. 

For instance Coke Cola has never changed there logo. Pepsi on the other hand changes there logo about every decade, this is a sign that the company is not doing well, not that it is innovative and wants to rejuvenate its look.

I personally think that Pepsi should have stopped in 1973.

From the 1930s through the late 1950s, "Pepsi-Cola Hits The Spot" was the most commonly used slogan in the days of old radio, classic motion pictures, and later television. Its jingle (conceived in the days when Pepsi cost only five cents) was used in many different forms with different lyrics.

In the 1970's there was the 'Cola Wars' and all across the UK, supermarkets where having challenges. Customers did blind tests and people in general preferred Pepsi. Still to this day Coke outsells Pepsi worldwide. Only in Russia did Pepsi outsell Coke but it was undercut once the cold war ended. In 1972 PepsiCo struck an agreement with the Soviet Union and was allowed marketing rights and exportation on Stolichnaya vodka in exchange for the Soviet to market Pepsi. This exchange led to Pepsi-Cola being the first foreign product sanctioned for sale in the U.S.S.R. Pepsi-Cola and its relation to the Soviet system turned it into an icon.
