MTV has been an influential force on pop culture and it is important to note which tactics they use to spread their messages to the youth of today. The ads in the above gallery are from two different campaigns. The first three images are from a Portuguese campaign to promote condom use and the prevention of HIV. The last couple are for a recent North American campaign to boost viewership.
In both campaigns, there is one obvious similarity: the use of sex and sexual imagery to provoke interest and intrigue. Whether using sex to sell is ethical or not, when it is helping to prevent the spread of HIV, I think it is wise to consider both sides of the debate. The end may just justify the means.
