This isn’t musical at all, but it’s interesting. Mountain Dew and Dunkin Donuts have both turned to social media to get consumers creating and promoting their new products. Mountain Dew is testing three experimental flavours of soft drink: Distortion, Typhoon and White Out. Each flavour has its own Facebook and Twitter profiles, with fans in charge of building word of mouth behind them to decide an ultimate winner. Meanwhile, Dunkin Donuts got people to submit ideas for new donuts, and has weeded 90,000 entries down to 12 finalists, with an online vote to decide which gets sold in-store. For its name alone, we’re going with Much A Do About Nut Things.
