Answer: Yes it can.
Step-by-step explanation:
Young people have for ages looked up to the media to tell them what is trending and what isn't. The media therefore has a very strong influence on how young people behave because in telling them what is trending, the young will want to engage in those trendy actions so as not to be left out socially.
If violence is glorified in the media therefore - through music, movies, series or text - young people might pick up on this and think that violence is trendy and so will be more likely to engage in violence. If for instance young people see a music video where guns are being brandished by other young people, they will think it is okay to have guns.
Violence in the media can indeed have a negative impact on young people.
