Very good point. When I took WUNO in San Juan to all-news around 1983 we were up against Mike Joseph's WKAQ, which had been all news for half a decade and had had a morning 6 AM to 9 AM news block for nearly 30 years. And they had one of the two biggest TV stations in the same building.It depends on what the reporters do. If they go out, cover stories, and provide audio, that function can be done by TV. As long as there are live anchors reading the news, the audio is just an accessory to telling the story. It's obviously more interesting with actual quotes, but the story can be told without it.
We got all the non-local news via AP, and most of the local news that way, too, as both AP and UPI had local bureaus. We also got open-air police and fire and government service radio reports. Added in were "correspondents" who were in the local governments of the six main municipalities (like "counties" on the mainland) and authorized by them.
Our feature was to use reverse phone directories and call until we got a neighbor or business next door or someone who was an eye witness to describe what they saw on the scene. Our anchors were very good at that type of "man in the street" interview and it gave us a very real local feel.. Out approach was very "street" in all aspects, so that gave us the flavor we wanted.
The result is that we had someone on the scene 30 minutes to 45 minutes before the "other station" even if they were not a professional reporter. With San Juan's traffic, sometimes we had on-scene descriptions of fires, protests, big accidents and other such events as much as an hour ahead of the traditional all news station and within less than a year were beating them.
