Quarterly data for 1977‐1994 on alcohol consumption and advertising are used to estimate a differential demand system, including explanatory variables for broadcast advertising and print advertising. The model explains the growth rate of per capita consumption dependent on explanatory variables for prices, real income, demographic changes, and real advertising by media and beverage. Empirical results also are reported for total consumption of pure alcohol. The results for the three beverages and total alcohol indicate that advertising has little or no effect on demand. The empirical evidence thus supports the notion that regardless of media, advertising affects mainly brand shares.
