Final answer:
An elevator pitch is a short statement that encapsulates the purpose and character of a project, meant to be relayed quickly and effectively.
Step-by-step explanation:
A short statement about the project that captures its purpose and character that could be relayed in less than a minute is called an elevator pitch. An elevator pitch effectively serves to draw readers in with a concise overview, often incorporating an anecdote, a question, or a compelling description. The purpose of the elevator pitch is to provide a brief introductory explanation of a project, capturing the scope and tone, and sometimes using narrative elements or media to make the message memorable. In the context of campaign messaging, the same concept applies, where messages are crafted into succinct "30-second sound bites."
