How does the news spread?

Can somebody explain how the news are spread? For example how Bloomberg and Reuters get the numbers? Do they receive a fax/email/phone call from the authority that is responsible for that report few second because the official announcement? And why, for example, the NFP number is released by both Bloomberg and Reuters at exactly 8:30:00, and why not one of them release it at 8:29:59?

Yes, but this thing cannot happen for all the reports, or it can? Have highly secured areas to announce to the reporters the news and then have a count down to release them. Maybe this is normal for NFP, but what happens with the other news reports?
