Sorry AnFI - I missed your snide little reply to John's post - no more than I have come to expect from you.
John, I take your point but maybe shot variation would be preferable to the same picture where nothing is happening (usually because it is so far after the event) whilst the newsroom anchors fill TV hours with, usually, pointless speculation.
I based my opinion on countless hours of day and night searches with daytime TV/FLIR where the same POV was distinctly undesirable and long periods of hovering, especially at night with few references, were both fatiguing and heavy on fuel burn.
I suspect the other problem with the news gathering, especially in the US, is that every channel will have a camera helo in the air, all vying for the best shot.
