A study has revealed that the most popular messaging app in Brazil is WhatsApp. Research conducted by Ilumeo and NovaSB, showed that over 95% of Brazilian internet users used the app. This was followed closely by Facebook on 87% before a fall to 50% of people using Skype. Nearly 76% of Brazilians use mobile messaging apps, meaning that around 60 million people are expected to be using WhatsApp this year. However, there is more good news for advertisers, after a report last month showed that over half of messaging app users in Brazil said that they would be open to receiving adverts in exchange for keeping the cost of using the apps, free.
