UFOs are in nearly every topic such as lost twin phenom, but as background/scenery, not as focus. Not foreground anymore.
I guess my impression has been that there has been a net gain in minutes of air time mentioning UFO's in any context.
I'm not sure there's any comfort or huge significance to be taken from their being more "background" in a given story.
In a way, they become the more insideously injected into our culture as part of the norm, wallpaper, woodwork, given.
