Answer:
As this would be a program for children so I would take 5 to 6 kids which will act in the advertisement.
Advertisement will start by showing 5 to 6 children playing in a ground, they are playing and all are looking very happy, suddenly one child stops playing and ask time from other kids again and again. This creates frustration to other kids. All other kids come to that kid and ask why you are interrupting the play and asking time again and again. That kid says that I have to go home and watch my favorite children show on the TV and tells about the qualities of the show very briefly and all kids left playing and went home to watch that show. This will surely persuade the audience to watch that show.
