Teenage Kicks Campaign:
The video of a teenager giving birth at school is filmed on a mobile phone, in order to shock teenagers into thinking twice about pregnancy and to promote safe sex. The video is quite explicit but really drives the message home.
Anti Slavery International Print:

This anti slavery print campaign reads: If your offended by this advertisement, you should be. No one should be treated like this. This print ad shows the appropriateness of using shock language, it proves that when the subject is correct it is appropriate to use shock language to offend an audience into reading on with intrigue.
Irish Anti - Speeding Campaign
This anti speeding campaign is very explicit with the way it is trying to portray its message to its audience. I am a little unsure if these type of ads for speeding really work anymore; so I would perhaps consider this an an inappropriate example of the application of shock tactics.
Barnados - One of Many Shock Campaigns
This is one of many shock ads that Barnados have released over the number of years. I've personally become a little de sensitised to these kind of ads after seeing them so often; but this one is a little different. All of the comments that make up the ad are up from comments that have been made from the public on chat rooms and other online social medias. It gives it a real sense of reality, making you start to think about what people are willing to say and do; and how extremist people's views can be.
