Social networking sites have become increasingly popular among teenagers since the 2000s. These sites allow teenagers to create profiles, connect with friends, and engage in online social interaction. While some argue that social media simply provides another venue for existing teenage interests like identity exploration and partner selection, others warn that aspects of online communication like persistence and invisible audiences can intensify risks like bullying. Overall, research suggests that social networking does not fundamentally change teenage behavior but may amplify existing social issues in online spaces.
