What type of advertising involves using promotional items to enhance brand presence at events?

The correct answer is related to the practice of enhancing brand presence at events through the use of promotional items, which is a key characteristic of event marketing. This form of advertising specifically focuses on engaging consumers in a direct and interactive way during events such as trade shows, fairs, or sponsorships. By providing promotional items—like branded giveaways, merchandise, or samples—companies can create memorable experiences for attendees and strengthen their brand identity.

Event marketing allows businesses to create a tangible connection with their audience, fostering brand recognition and loyalty. It differs from other advertising types, which may not involve direct interaction or the physical presence of promotional materials at events. Social media advertising and direct mail advertising focus on online and mail campaigns, while institutional advertising generally promotes the organization as a whole rather than specific products at events. Thus, the unique characteristics of event marketing make it the most appropriate answer in this context.
