Have you noticed that many financial news reporters can't deliver their narrative properly?

Question

When TV and radio financial commentators speak they seem to interject every other sentence with annoying utterances of ..."ah".

EXAMPLE: "Stocks ...ah...took ...ah ...a plunge today with ...ah...word of ...ah... impending...ah...ah..." Good grief this is annoying! Did these people not take any public speaking courses, or is it a subtle display of arrogance? Some don't exhibit this poor habit but the majority do!

Answer 1

It's because they read a text that scrolls down a tv screen and there's a delay from the control of the scrolling speed. It's hard to fallow the exact speed variations of a person's speach.
