NG button

It's an NG mark, short for "No Good." It's mainly used to indicate a mistake or something incorrect.

It's frequently used in broadcasting or filming to mark a flawed scene. It's also used in schools or workplaces to indicate something wrong.

Originating from Japanese broadcasting culture, this symbol has become a universal indicator of "not suitable" worldwide. It's widely used, especially in media production, as an abbreviation for NGS (No Good Shot).

First used in the Japanese TV broadcasting industry in the 1950s, this term has become an important expression in social media and digital communication today. It has evolved into an effective communication tool that can indirectly convey negative meanings.
