In sales terms I've met pitch for a lot of time as a sort of presentation. But what is this little difference between the presentation and pitch in term of sales or other public speech in a conference for example.
A pitch is a specific kind of presentation, typically:
- The pitch presentation is a 20-minute (or so) slide presentation, usually done live but with either PowerPoint or Keynote slides in the background, that tells investors about a new business.
Sales pitch in the modern commercial advertising sense is from 1943, American English, perhaps from the baseball sense.
In a presentation you are just literally giving facts. Usually this is to arm someone with information about a decision they will ultimately make, or information they need to learn. In a pitch however, you are calling them to take the action you want them to take. It is, by nature a persuasive argument.
