Motion interpolation on a TV ad

Recently I saw a TV ad about SMS amber alerts. The ad showed a child abductor being caught because someone who got the SMS tipped the police off. The video appears to be interpolated from a low framerate like 24fps to full 60fps. How do I know? because the motion interpolater left just as much artifacts as the 120fps interpolater in my TV. I do not know how exactly this happened but the most probable reason is that they shot the commercial at 24fps then realized that 24fps looks too fake and ruins the horror effect of the ad so they interpolated it to 60fps. This relates to a disturbing trend in modern video production - 24fps. People seem to be using it (or dropping higher framerate sources to 24fps) for no real reason. All the deficiencies of old video like low dynamic range and low resolution have been addressed with improvements in video camera technology. Still, less than half of today's TV ads and prime time shows are full 60fps. We can only hope that this will be just another fad that will fade away like the overuse of primitive digital effects in the 80s.
