Which term describes an event where various companies showcase and sell their products?

The term that describes an event where various companies showcase and sell their products is a trade fair. A trade fair typically gathers numerous businesses within a specific industry to display their offerings and connect with potential customers, partners, and suppliers. The focus is often on networking, lead generation, and market trends, making it an interactive experience for both exhibitors and attendees.

While an exhibition can also involve showcasing products, it is usually broader and might not have the sales emphasis typical of a trade fair. A product launch refers specifically to the introduction of a new product to the market, rather than a gathering of multiple companies. A convention is a larger meeting of people that may center around discussions, workshops, and networking; it does not automatically imply that products will be sold or showcased in the same manner as a trade fair would.
