Market Share Data
Market share is the percentage of sales (by value or volume) that a brand or company has for a specific product or category.
Note: Market share calculations can range from specific products (i.e. Vanilla flavored ready-to-drink iced coffee) to extremely broad industries (i.e. food and beverage). Be sure you are aware of which industry segment(s) a report includes.
