Emojis have swiftly become a mainstay of Millennial and teen communication, and now they’re working their way into marketing. AT&T’s holiday campaign includes an Emoji Carols site, where visitors can create animated versions of holiday songs using emoji symbols. An emoji customized to look like themselves can also be included. Once completed, these visual songs can be shared on social media and via email. The campaign will be promoted on social platforms and through a BuzzFeed partnership. (MediaPost)
