How do you make an ad for a porn site G-rated? Pornographic website Pornhub posed just this question to users, resulting in 15 innuendo wrought finalists.

In the search for an innovative thinking for the site’s next global advertising campaign, Pornhub unveiled the 15 finalists last week.

Entrants had to come up with a “G-rated” and “safe for work” design that could be featured on a number of outlets.

The winning entry will earn the title of creative director for the website with a one year paid contract.

Viewers can vote for their favourite design out of the fifteen finalists. Check out some of the entries below via Pornhub’s Tumblr site.

According to the tumblr site set up for the competition, the creative brief is: “Traditionally, porn has been a taboo subject – but the fact is, over 35 million people visit Pornhub.com everyday! How do we reach the next 35 million? We need a national advertising campaign that can be channeled through mainstream media. We need to spread the word that porn has something for everyone, and Pornhub should be your go-to site for free videos whenever and wherever you want.

“Why is this a challenge? As opposed to internet advertising, where you can show some nudity and people will click, conveying our message through mainstream media will be challenging. We need to promote Pornhub through a G-rated ad campaign without risk of offending, while still being a bit cheeky and fun.”

Entries for the competition closed March 31, 2014 with the fifteen finalists released last week.
