Its easy and cheap to add a US story as opposed to a story in Botswana about drought conditions or elephant poaching or some other country where a reporter has to be dispatched yada yada. IMO the reason US stories are being use is because of the highly developed mass media in the US. Hundreds of local stations across the country. So live pictures are easily available to pop up on the screen in seconds to any broadcaster due to the affiliate news services, like NBC News Channel and FOX News EDGE amongst others. They enables the sharing of footage and live images. So thats why the frequent storm/tornado coverage. Someone on London does a VO over the hundreds of hours of available footage from the affiliate services. Or a building collapse in Philly will have 4 to 5 local affiliates covering for the Philadelphia market, the live helicopter pictures or street side video is readily available and streaming around the world in seconds. But in the grand scheme of things that story has no relevance to anyone except those in the Philadelphia area. Its cheap and easy to fill time with American daily horror stories, such as mass shooting etc.
Australian tv is notorious for these "Breaking News" filler stories.
