Social media in 2025 is the backbone of modern digital life — a set of global ecosystems that influence how people communicate, discover, shop, learn, and entertain themselves. Billions log in every day, turning these apps into platforms that shape culture, power commerce, and distribute information at a previously unimaginable scale.
