internet. Most of the vendors' websites require an age of 21 to enter, but there is no restriction besides simply entering a birth date. A study done by the American Journal of Public Health concluded that Boston train passengers between the ages of 11 and 18 saw an alcohol-related advertisement every day. There have been studies similar to this, which supports the allegation that underage consumption of alcohol is in correlation with the exposure of alcohol ads. In response, many cities have recognized the effect of alcohol-related ads on adolescents and in some cities these advertisements have been banned on public transportation. Peter Anderson and his colleagues performed longitudinal studies and concluded that "alcohol advertising and promotion increases the likelihood that adolescents will start to use alcohol, and to drink more if they are already using alcohol." Elizabeth D. Waiters, Andrew J. Treno, and Joel W. Grube's discussions with a sample of youth, ages 9–15, support this claim. They found that these youth saw the purpose of beer commercials is to urge people to buy the product based on not only its quality, but also on "its relationship to sexual attractiveness." They see the "attractive young adults drink beer to personally rewarding ends" and the "youth-oriented music" and are influenced to drink alcohol. The National Household Survey on Drug Abuse reports the rates of binge alcohol use in 2008 were 1.5 percent among 12 or 13 years old, 6.9 percent among 14 or 15 years old, 17.2 percent among 16 or 17 years old, 33.7 percent among persons aged 18 to 20. In 2009, the rates for each group of underage alcohol usage increased by a fourth. According to 2001 College Alcohol Study (CAS), continuous alcohol promotions and advertisements including lowering prices on certain types of alcohol on a college campus have increased the percentage of alcohol consumption of that college community. Alcohol advertising on college campuses have also shown to increase binge drinking among students. However, it is concluded that the consistency of these special promotions and ads could also be useful in reducing binge drinking and other related drinking problems on campus. (Kuo, 2000, Wechsler 2000, Greenberg 2000, Lee 2000). Results from one study indicate that beer advertisements are a significant predictor of an adolescent's knowledge, preference, and loyalty for beer brands, as well as current drinking behavior and intentions to drink (Gentile, 2001). Television advertising changes attitudes
