The question of whether an idea is necessary in a logo is a controversial topic that provokes discussions among designers, marketers and entrepreneurs. A logo serves as a visual symbol that represents a company or brand. Its main purpose is to communicate the identity and values of a given entity quickly and efficiently. Looking at the logo, the viewer should immediately recognize what the brand represents, even without a deeper analysis of the idea behind it.
Sometimes a simple, abstract symbol or graphic element can be enough to effectively identify a brand. An example would be the Nike logo, which includes a simple swoosh. Although this logo does not have an explicit idea, it has become a symbol of sports fashion around the world.
Sometimes the goal of a logo is to convey a specific idea or message, while other times the main task is only to identify the brand. An example would be the logo of a sports team, which can serve to easily recognize the team without complicatedly communicating an idea.
Importantly, there is no unequivocal answer to the question of whether a logo must contain an idea. It depends on the nature of the brand, its goals and communication strategy. Some brands prefer simple and abstract logos, while others prefer complex logos with specific ideas.
