Red Balloon is an English language learning center in Brazil for kids. In their latest campaign by Ogilvy Brazil, brazilian kids spotted many celebrities tweets with English misspellings and replied from the Red Balloon account presenting themselves, correcting the mistake(s) and attaching a picture of them. A really cool idea that costs literally nothing to execute. Of course, you need to put a small budget to film a case study because it is the only way to start spreading the word specially that no celebrity replied so far. The kids tweets didn’t go viral they barely got few retweets but the case study video below has high viral potential.
