🧩 Background & Origin
The term “GB” started gaining popularity in early SMS culture (2000s), when character limits encouraged shorter messages. Typing “Goodbye” every time was too long, so people began abbreviating it to “GB.”
Later, as social media platforms like Facebook, WhatsApp, and Instagram emerged, the abbreviation carried over — evolving beyond “Goodbye” into broader meanings like “God Bless” and “Gigabyte.”
Meanwhile, technical communities (like IT and mobile users) already used “GB” for “Gigabyte,” which sometimes led to confusion between slang and technical talk.
