Alcohol advertising on college campuses
Many college campuses throughout the United States have some form of alcohol advertising including flyers on bulletin boards to mini billboard signs on college buses. It is so prevalent on college campuses especially because college students are considered the "targeted marketing group," meaning that college students are more likely to consume larger quantities of alcohol than any other age group, which makes them the prime consumers of alcohol in the United States.
