The promposal trend, which we spotted last year, has only been growing and now brands are getting in on the public “will you go to prom with me” spectacles. MTV launched “Promposal Mania” last month, orchestrating promposal stunts with pop stars and broadcasting them on Snapchat and Periscope. Sour Patch Kids has asked teens to submit their promposal stories on social, and is hosting a prom for the winners of the competition. (The Drum)
