Social media is one of the fastest-growing industries in the world today. A study carried out by the PewResearch Center showed that 92% of teenagers go online daily. The wide use of social media has changed nearly all parts of teenagers’ lives.
High school student Elly Cooper from Illinois said social media often reduces face-to-face communication. “It makes in-person relationships harder because people give attention to their phones instead of persons,” Cooper said. Yet, some people believe social media has made it easier to start relationships with anyone from anywhere.
The rise of social media has changed the way teenagers see themselves. The 19-year-old Essena O’Neill announced on the social networking service Instagram that she had stopped using social media. She thought she had gotten lost in appearing perfect online. Negative comments can also do damage to a teenager’s self-esteem (自尊). Teenagers who get negative comments can’t help but feel hurt. In particular, some social media apps such as Yik Yak may provide opportunities for cyber bullying (网络欺凌).
However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site YouTube. “Social media can help people show themselves and their talents to the world in a way that was never possible before,” Korsos said.
But Korsos realizes that social media has become a distraction (让人分心的事). “Social media is not all necessary, though it helps people connect with their friends and know each other well anytime.”
