The new trend in advertising is real time ads and real fact ads. You can advertise in live thanks to the social media and create content with real facts from your audience. A good example was the Old Spice viral video campaign where the actor was responding to the comment on youtube with a real video. It's a good opportunity to create interactivity and recreate interest around the same concept but with fresh content.
