Tweets power vending machine at SXSW

Twitter engagement from concertgoers, and fans watching the live stream remotely, affected the outcome of the opening act, special effects, onscreen visuals and encore song at Doritos’ interactive concert at SXSW. Hashtag #BoldStage powered the interactivity on Doritos’ concert stage, a 62-foot ‘vending machine’ with a four storey screen that was used to encourage people to tweet and showcase photos.
