Coca-Cola's Advertising (P.2):
During the 1980s, Pepsi-Cola ran a series of television advertisements showing people participating in taste tests essentially demonstrating that: "Fifty percent of the participants who said they preferred Coke actually chose the Pepsi". Statisticians were quick to point out the problematic nature of a 50/50 result; that most likely all this really showed was that in blind tests, most people simply cannot tell the difference between Pepsi and Coke. Coca-Cola ran ads to combat Pepsi's ads in an incident sometimes referred to as the cola wars; one of Coke's ads compared the so-called Pepsi challenge to two chimpanzees deciding which tennis ball was furrier. Thereafter, Coca-Cola regained its leadership in the market.
Selena was a spokesperson for Coca-Cola from 1989 till the time of her death. She filmed three commercials for the company. In 1994 to commemorate her 5 years with the company, Coca-Cola issued special Selena coke bottles.
In an attempt to broaden its portfolio, Coca-Cola purchased Columbia Pictures in 1982. Columbia provided subtle publicity through Coke product placements in many of its films while under Coke's ownership. However, after a few early successes, Columbia began to under-perform, and was dropped by the company in 1989.
Coca-Cola has gone through a number of different advertising slogans in its long history, including "The pause that refreshes", "I'd like to buy the world a Coke", and "Coke is it".
In 2006, Coca-Cola introduced My Coke Rewards, a customer loyalty campaign where consumers earn virtual "points" by entering codes from special marked packages of Coca-Cola products into a website. These points can in turn be redeemed for various prizes or sweepstakes entries.
