a sales pitch
A 'sales pitch' is a way of presenting something or a way of communicating which is intended to convince you to buy something. An 'elevator pitch' is a short sharp presentation of a couple of lines usually used to spark interest in what you or your organisation does. These are expressions you will use mostly in professional situations.
