Examples of how Media can influence social behaviour?

[PokéYetti]

I have to give an example on how Family, and Media can influence social behaviour, and for family I wrote that it is important for some families to eat together at the table and socialize at dinner. I don't know what I'm supposed to write for the media one though Help?

If you have ever watched the movie M: the media gets the population of Berlin to hunt down a child murderer within itself (talk about overkill).
