The country's No. 3 beer brand said the horses will not play a role in its traditional advertising for the season, although the company added later Monday that they will be featured in spots promoting responsible drinking. According to Beer Marketer's Insights, Budweiser had 7.6 percent of the market last year, down from 14.4 percent a decade ago. The erosion has been the result of the growing popularity of light and craft beers, said Eric Shepard, executive editor of the industry tracker.
