Social networking sites originated in the mid-1990s with sites like TheGlobe allowing users to interact through chat rooms and share information. Sites grew rapidly in the early 2000s with the introduction of Friendster, LinkedIn, and MySpace which allowed users to connect with friends and find others with similar interests. While social media helps people stay connected with family and share photos, it also poses dangers like unknown strangers friending youth, cyberbullying, and companies' potential loss of money if users abandon sites. Statistics can help track safety progress and identify at-risk age groups needing attention online.
