Durex wants to promote condom use to people who enjoy experimenting sexually but don't typically use condoms. They partnered with a social media site where users report details of their sexual encounters, including condom use. Durex customized messages that would appear for users who reported multiple encounters without condoms, with the goal of encouraging condom use in a fun, non-obtrusive way. Outdoor ads were also placed in locations identified as popular places for sexual encounters based on data from the site.
