Contests, giveaways and sweepstakes have always been a great way to get a brand in front of a large number of people, but interest in the campaign usually wanes as soon as the winner is announced. To combat that trend, many contests have turned into hunts for the next online cewebrity, where the winner gets a chance to extend their 15 minutes of fame through the sponsor’s social channels (and on the sponsor’s dime) in exchange for extending the life of the campaign in the process.
