What does a press release usually have that a news story should not have?

The correct answer is: agenda

Explanation:

The press release is an official statement on some very specific topic, it is a concise text that informs of a precise news. How it does not have a guarantee of automatic publication and, even less, of a diffusion in all its extension, it must be characterized by “making known” an unpublished and pertinent information so that the Journalists and the Media they represent feel interest for publishing it. While the news is a report that is given about a recent event, it does not have to be linked to an event, it can simply be an informative and newsworthy document.
