Thorny Pitches

Do you call it a logline or a premise or a one-sentence pitch? And by whatever name you call it, is it really that much different?

The logline's history starts with scriptwriting, so if I have a novel, do I want to call it a logline?

The premise is a one-sentence summary of a novel, which may or may not be nearly the same as the one-sentence pitch.

Whichever one you think you're writing, it has to be catchy. Ever feel sorry for all the industry professionals who have these short pithy sayings...
