Other forms: bulletins
A bulletin is a short official update telling people what is happening now. The news bulletin on the hour, the hospital's one-line statement about a patient, the weather bulletin read out during a storm.
Short and official — that is the whole flavour of the word. A long report is not a bulletin. In broadcasting, the bulletin is the brief summary between programmes, and the newsreader reads it. Clubs, churches and societies put out a bulletin as a printed or emailed newsletter for members. And in American English, a bulletin board is what British English calls a noticeboard.

Bulletin came into English straight from French bulletin. Behind the French word stands the bull, the sealed document an official body sends out. That is why a bulletin still carries a stamp of authority, however few lines it runs to.
