Advertising is everywhere in the media that high school students use, influencing how they think and what they value. On the bright side, advertising can be helpful. It introduces students to new products, technologies, and opportunities they might not have known about. Ads also help keep content free on many platforms, allowing apps, websites, and social media to be accessible at no cost. But there are downsides too. Constant exposure to ads can make students think that happiness comes from buying things. This focus on buying can take attention away from more meaningful activities and goals. Ads for unhealthy foods can also lead to health problems, like gaining too much weight or developing other issues. To deal with both the positives and negatives of advertising, it’s important for students to learn how ads work and develop critical thinking skills. By understanding both sides, students can make smart choices, enjoy media responsibly, and reduce its negative effects.
