There is no real agreement on what a global brand is.A typical definition would be a brand that is marketed under the same name in multiple countries with similar and centrally coordinated marketing strategies.There are,however,some selected global brands that don't have the same name but share some marketing program elements(e.g,Mr.clean also sells under the Mr.Proper and Maestro limpio names among others)A number of studies have attempted to quantify the definition of a global brand.Typically,sales need to exceed 1 billion a year with a minimum amount generated outside of the marketer's home region or country( varying from 5 to 20%). Presence is also required in all of the megamarkets of the word.These definitions restrict the number of brands to considered global to a few dozen(e.g,ACNielsen's study found only 43 brands that satisfied their narrow criteria).What's common in these definitions is the multimarket reach of peoducts that are perceived as the same brand wordwide both by consumers and by internal constituents.
