What is the importance of these cues in delivering the news report?

There are four basic methods (sometimes called styles) of presenting a speech: manuscript, memorized, extemporaneous, and impromptu

Explanation:

The word manuscript is the clue to the style. The speech is written and the speaker reads it word for word to the audience. Originally, it was done from the hand-written paper manuscript. Today the manuscript style is common, but the paper is gone. Who reads the speech to the audience? Newscasters and television personalities. In the old days, the manuscript was hand-lettered on cue cards, which were held next to the camera lens. Then paper scrolls, like printed piano rolls were used, especially in Soap Operas. Today, a special teleprompter (working like a periscope) is attached to the camera so the newscaster is looking at the lens while reading.  (Hope this helped, also I would love if you could give me a rateing, thx)
