As part of its plan to brand each Friday night during October 2011 as “Coca-Cola Family Night,” the folks at Coca-Cola’s My Coke Rewards loyalty program created a handful of trivia games and virtual scavenger hunts, rendered interactive via live Twitter challenges and chats. Instructions for the challenges were conveyed via Twitpic, which added a further visual component to the branding. Was there gentle trash-talking through the #MyFamilyRules Twitter hashtag? There was indeed.
