Social media is fundamentally changing how people communicate and interact. It is not a fad but a revolution in how information spreads and relationships are formed. Social networks now reach over half the world's population, especially those under 30, and people are increasingly meeting and connecting through these platforms rather than through traditional offline means. The rise of social media shows no signs of slowing and will continue reshaping how businesses market, how people share information, and how we build relationships in the digital age.
