Back in March, Facebook added the ability for users to respond to individual messages within a Messenger thread with Reactions - their emoji response set which they first rolled out to Facebook proper back in February 2016. At the time, we noted that this may actually be a better use for Reactions than in the main app, as Reactions in Messenger serve a purpose, providing an easier way to respond to individual messages within a stream - which is particularly relevant for fast-moving Group chats.
As it turns out, Reactions have proven popular on Messenger, with Facebook reporting that over two billion Messenger Reactions have been sent within the first two months of their availability.
For context, Facebook says that Reactions in their main app were used 300 billion times in their first year, which equates to around 25 billion uses per month, so Reactions in Messenger aren't quite at the same pace yet. But then again, the use-case is different - there are already around 4 million Likes submitted per minute on Facebook, whereas Likes have not been available within Messenger in the same form before.
To mark the milestone, Facebook has shared a new infographic which breaks down Messenger Reactions use, including the most popular Reactions by country, the most frequently used Reactions in different exchanges and usage amongst demographic groups.
