Gatorade

 

J. Robert Cade was a physician and the lead inventor of Gatorade. When he was working in the renal (kidney) division of the University of Florida College of Medicine in 1965 when the Gators coach came to him with a question.

He wanted to know why his football players didn't need to urinate after a game. The answer was dehydration, a subject that had really been studied in relation to sports before.

The philosophy at the time was that athletes should not drink water during strenuous activities. The idea was that it make them sick to their stomachs. 

Cade and his team began doing research and were surprised to find that players could lose as much as eighteen pounds of water weight during a three-hour game played in Florida heat. 

The researchers then turned to experiment with a drink that could replace not only fluids but electrolytes. An electrolyte is a substance that produces an electrically-conducting solution when dissolved in a polar solvent, such as water.

The first version tasted terrible and further experiments were concerned with taste. Eventually, they hit on some effective strong flavors. 

The University researchers initially considered naming their product "Gator-Aid" as something that could aid the Gator athletes. But using the "aid" suffix might require proving that the product had a clear medicinal use which would require clinical testing. Using "ade" (as in lemonade) would allow it could be classified as a soft drink.

Though Gatorade is best known as a sports drink, it is also used for postoperative patients, colonoscopy prep, and children suffering from diarrhea. 

Gatorade's commercial success came with Stokely-Van Camp’s buying the rights to produce and market the drink. The Gatorade brand was purchased by the Quaker Oats Company in 1983, which, in turn, was bought by PepsiCo in 2000. The University of Florida gets 20 percent of the royalties and in 2015 reported that its total take from its royalties in Gatorade had risen to $281 million.

Gatorade is PepsiCo's fourth-largest brand based on worldwide annual retail sales and its biggest competition is Coca-Cola's Powerade and Vitaminwater (and Lucozade in the UK). In the United States, Gatorade accounts for approximately 75% of the market share in the sports drink category.
