it used to be, but now its just something they add so you don't think you are looking at a static screen. No news program uses an actual live feed from the radar anymore as the processed images look much better.
If you look closely, the sweep does update the screen.... every five minutes or so. Pay attention during your next severe weather event and you'll see it.

Nice overly slow fake radar sweep they've added to the map. 😂
