In our marketing course, we have a class on exhibitions and events, things like trade shows where many businesses of a similar type come together in one place and promote their goods & services to the many potential customers who visit.
Business English Pod
Business English Pod has a 4-part series of podcasts about trade shows, covering the typical activities and vocabulary of these exhibitions, as well as a lot of sales vocabulary and procedures.
