Which term describes major events where buyers have the opportunity to engage with suppliers about their offerings?

The term that accurately describes major events where buyers have the opportunity to engage with suppliers about their offerings is "trade shows." Trade shows are industry-specific events that gather suppliers and buyers under one roof, allowing for networking, product demonstrations, and the exchange of information. These events provide an excellent platform for businesses to showcase their products and services while facilitating direct interaction with potential customers, partners, and other stakeholders.

While conventions, exhibitions, and product launches may involve suppliers and buyers, they do not specifically focus on the same level of engagement and interaction as trade shows. Conventions are broader in scope, often including conferences and seminars alongside showcases. Exhibitions can encompass a variety of displays and booths but may not have the same connotation of industry-specific marketplace and sales discussions as a trade show. Product launches typically center around unveiling new products rather than broader supplier engagement. Thus, trade shows are the most fitting term for the described events.
