Company The corporation that owns the product line, such as Coca-Cola or PepsiCo.

Category The category refers to the type of beverage.

This study included: • regular soda (i.e., carbonated, sweetened soft drinks or pop); • sports drinks (i.e., non-carbonated, sweetened drinks marketed as appropriate to consume during physical activity) • fruit drinks (i.e., fruit-flavored, non-carbonated drinks with less than 50% fruit juice) • diet soda (i.e., low or no-calorie carbonated soft drinks with artificial sweeteners) • 100% juice (i.e., beverages that contain only pure fruit juice, with no added sugar or non-caloric sweeteners)

Brand The brand refers to the marketing unit.

• regular soda (i.e., Coke, Pepsi, Sprite, Canada Dry Ginger Ale); • sports drinks (i.e., Gatorade, PowerAde) • fruit drinks (i.e., Hawaiian Punch, SunnyD, Capri Sun fruit punch) • diet soda (i.e., Diet Coke, Diet Pepsi, Diet Mountain Dew) • 100% juice (i.e., Tropicana Orange Juice, Welch’s Grape Juice)

All ACV is similar conceptually to a z-score because it allows values from Commodity different scales to be standardized and then compared to each other. Volume This is useful in marketing research because the volume of sales for a (ACV) product in smaller stores can be compared to the volume of sales for the same product in larger stores. In this case, the ACV was calculated by taking the dollar amount sold of a beverage brand and category as a proportion of $1 million in total dollar sales in the supermarket as a whole.
