Pepsi-Cola is a company that manufactures various soft drinks.

Marty McFly was a drinker of Pepsi products, as was his future son, Marty Jr.

History

Below are a series of instances involving Marty and Pepsi:

When Marty arrived in 2015, there were no other cola brands visible to him except for Pepsi products. Pepsi Perfect was vitamin-enriched, and came in a bottle with its own built-in straw. Doc gave Marty a $50.00 bill, telling him to order a Pepsi at the Cafe 80's.

In 2035, Bistro Twenty/15 sold every Pepsi variety that was available between the end of the 20th century and 2015. The Pepsi varieties available were Pepsi, Diet Pepsi, Caffeine Free Pepsi, Caffeine-Free Diet Pepsi, Limited-Edition Crystal Pepsi, Pepsi Throwback, Pepsi Vanilla, Pepsi Ginger, Pepsi X Energy, Pepsi Lime, Diet Pepsi Lime, Diet Pepsi Lemon, Pepsi Kick, Pepsi Max, Pepsi XL, and Pepsi Perfect.

Behind the scenes

In the commentary on the DVD, Robert Zemeckis and Bob Gale discussed product placement, and said that they looked for products that had changed appearance between 1955 and 1985. While the Coke bottle had remained the same during that time, the Pepsi bottle's appearance had undergone several redesigns during the same period, and Pepsi products were featured as part of the first two films. Although the advertising agency wanted the reference to Tab (a Coca-Cola product) dropped, Gale commented that the joke was too good to leave out. A reference to a "cherry Coke" remained in the final production.

Ironically, Coca-Cola was featured even more prominently in the first drafts of the Back to the Future script than Pepsi was in the final version, and for entirely different reasons. In the first script, Marty accidentally spilled Coke into the power circuits of the time machine, and the resulting chemical reaction between the cola and the plutonium made it possible to generate enough electricity to power to make time travel possible. In addition, the script called for Marty to return to a world where Coca-Cola was the main power source.

In addition, the script called for Marty to return to a world where Coca-Cola was the main power source. Doc never mentions at any time on-screen that a Pepsi costs $45.00; he simply says "Go in [the Cafe 80's] and order yourself a Pepsi. Here's a fifty" as he hands Marty a $50.00 bill. If this had been the case, as of 2010, a 20 oz. bottle of Pepsi averages $1.50, so in order for inflation to suddenly surge to 666.66% per year, the economy would have to take a nosedive of Zimbabwean proportions.

After 1985, actor Michael J. Fox was signed to a deal to appear in Pepsi commercials.

Pepsi was not invented until 1898 (and Coke in 1886) so there were no colas in the 1885 setting for Back to the Future Part III. However, there is a Pepsi billboard at the Pohatchee Drive-In as Marty prepares to leave 1955.
