Social networking allows individuals to create public profiles, meet others with shared interests, and connect with friends and family. The first social network, Facebook, launched in 1997 and now has over 800 million users, with 50% logging on daily. Every 60 seconds on Facebook, 510,000 comments are posted, 293,000 statuses are updated, and 136,000 photos are uploaded. While social networks connect people and provide access to information, overuse can negatively impact productivity and relationships. Addiction is characterized by constantly checking for updates and prioritizing social media over real world interactions.
