SOCIAL MEDIA MINI CASE: in the Summer of 2013, Kraft

SOCIAL MEDIA MINI CASE: In the summer of 2013, Kraft Foods' annual tour of the Oscar Mayer Wienermobiles became a cross-country road rally called the Wienermobile Run. Consumers were encouraged to follow the promotion on social media like Facebook, Instagram, and Twitter, and share messages about the Wienermobile Run with their friends. The men and women who drove the six Wienermobiles, also known as Hotdoggers, were divided into teams. Each team's vehicle had its own name. Teams raced around the country to accumulate points. Drivers performed tasks or challenges submitted by the public on a website, wienermobilerun.com. The goal was to get consumers to engage on a deeper level with the Wienermobiles by introducing games in order to take advantage of a trend toward gamification. They also allowed consumers to use social media to request the Wienermobiles show up at their events to give consumers a more visceral experience with the vehicles.
