Now this is how you troll the media for a marketing campaign. New Zealand TV network Prime came up with a rather risque idea to promote the latest series of Billie Piper's Secret Diary of a Call Girl, by pranking a radio station eventually the entire nation, sending the fake scandal viral without spending a penny. Someone in that ad agency just got a massive bonus.Slightly NSFW, but it's about call girls, so you should expect that.
