90 THE POWER OF VISUAL STORYTELLING RadioShack used the Promoted Trend function on Twitter to ask people to upload a picture of them- selves stretching out their hand, along with the hashtag #ifihadsuperpowers and a tweet of what they would do with superpowers, for the chance to win a mystery prize. RadioShack then digitally added a superhero costume to the photo and tweeted the photo back to the users! Several of the photos were randomly selected to win prizes from the store or RadioShack gift certificates. Due to the success rate and impressive increase in fans and positive sentiment, RadioShack’s 2010 holiday campaign was selected from more than 200 entrants for the Forrester Groundswell Awards that year, winning top honors for its category “Business-to-Consumer North America: Energizing.”90 In 2013 Intel began using the hashtag #dothemath on Twitter, and it’s been the company’s most successful hashtag to date. Intel includes a staggering fact or com- parison, the hashtag, and an image. This really works well because Intel’s followers like to have their minds blown by geeky statistics, and it draws them into the conversa- tion. Intel has found that Tweets with numbers, statistics, and top-10 lists are generally recipes for success. Another great example of interactive Twitter engage- ment is a Valentine’s Day dialogue between Intel and Lenovo. Intel sent some of their partners custom Valentine’s Day image tweets. Lenovo was one of the first ones to respond. Intel said: “@lenovo Text us. #HappyValentinesDay!” Lenovo jumped right in with this reply and a picture of the flowers made out of tech gadgets: “@intel We got you these. Dont even need to put them in water.”
