Pepsi Co. wanted to launch an apple flavor of Mountain Dew. Thinking that having online users name their drink would be a masterstroke in marketing, they launched a massive campaign to promote the contest. Things were going great until 4Chan got a whiff of it.
Pretty soon, names like Diabeetus, Gushing Granny and ‘Hitler did nothing wrong’ started to lead the race. Pepsi had to choose between promoting Nazis or terminating the contest. They chose the latter and have not launched that apple flavored drink in the market to date.
