Alcohol and TV.

According to a voluntary standard adopted in 2003, alcohol companies agreed not to place any ads on TV programs where more than 30% of the audience was younger than age 21. However, a survey of television programs popular with youths shows that 25% of the programs still featured ads selling alcohol. Studies have shown that exposure to alcohol marketing increases the risk that children and young adults (under age 21) will begin drinking, and those who do start drinking will drink more and do so more often.
