What is a common application of promotional materials?

Promotional materials are primarily used to communicate and attract attention to a product, service, or event. Designing advertisements and flyers falls directly into this category as these are the formats through which businesses promote their offerings to potential customers. Advertisements aim to engage the audience, convey key messages, and drive sales or attendance, making them a fundamental aspect of marketing strategies.

Creating technical specifications, illustrating trends and data analysis, and producing 3D models in CAD serve different purposes that are more focused on technical communication and design rather than promotion. These activities are essential in fields such as engineering, data science, and industrial design but do not directly involve promoting products or services to consumers. Thus, the design of advertisements and flyers is the most relevant and common application of promotional materials.
