Edit (12 Sept 2013): I removed dead links to Bing dictionary and replaced with working links for other dictionary websites. I also removed dead Monster link for sales movies, and added links for 2 other articles on sales movies.
Sales is the activity of trying to sell: to convince someone to buy your product or service.
For most businesses, this is their most important activity. No sales = no money!
So sales can be a high-pressure job and involve a lot of human drama: a great recipe for movies!
As a result, there are many movies in English about people in sales, and watching them can be a great way to learn English AND learn the business (and vocabulary) of sales.
"But I'm not in sales!" you might say. That doesn't matter: ALL business is sales. You always need to be able to convince people to accept what you can offer. For example, in a job interview you are selling yourself (your skills, talent and effort) to a company, in return for a salary and benefits.
So here I offer some links on movies about the world of sales.
Lists/Discussions About Sales Movies
These movies are hosted on a Chinese website and might have Chinese subtitles, in case you don't understand some of the words.
(Edit 20/3/2012: these movies might move or be deleted. It depends on the video website.)
