Hats off to cookie brand Oreo. Their Facebook feed is awash with playful nods towards the internet zeitgeist, but their latest offering really encapsulates viral marketing at its peak.

Yesterday’s ‘big announcement’, the release of the iPhone 5, kicked off a raft of blog posts, tweets and memes, many skeptical of the new model’s ‘new’ features (we’re saying nothing). Oreo was quick to jump on board, posting this image to its Facebook feed and leaving onlookers in no doubt about the its ability to respond quickly and cleverly to relevant cultural developments. Top marks.
