The term that best represents this type of information is this: Announcement.
What is an announcement?
An announcement is a formal or informal statement that is made to the public with the intent of giving information about something that has happened or that will happen. It is a way of communicating important news to a large group of people.
This is the case when Gary reports information that is not previously known such as the score from a local high school football game or an announcement that a high-ranking politician has been convicted of a crime.
