The power of this ad lies in the headline, which suggests that the TV is not harmful to humans as it is located in every hospital room.
This ad is aimed at all social groups, especially those who have time to watch TV around the age of 40-65. The argument used to say that TV is not harmful is not valid, but neither does it contradict the context. This ad violates the cultural norm that television can be harmful to health.
This ad is selling health and comfort.
