I thought social media was something to do with connecting users on the web, not printing statistically relevant names on products.
Jim finds a Coke with his name on it!
Jim says, "Hey, that's pretty neat."
Jim posts an Instagram of him next to his personal Coke.
Jenny sees Jim's post and comments -- "Hey, that's pretty neat. Where can I get one with Jenny on it?"
Coke advertised their product. Some people got excited, and told their friends on social media. Just like other things. Coke didn't do anything special with social media, they just counted on people using it. Big deal.
