As Messenger creeps up towards the one billion active user mark, details have emerged revealing Facebook's plan to introduce advertising to the chat platform by June.
According to an internal Facebook document obtained by TechCrunch, Facebook will let businesses send ads as messages to people who previously started a chat thread with that company.
Facebook also has a suggestion on how to approach the introduction of adverts. The document advises businesses to kick off conversations with consumers now, so they'll be able to send ads once the feature arrives.
Over the past year, Facebook has launched a number of features to encourage conversations between consumers and businesses, such as Businesses on Messenger.
Facebook doesn't appear to be too concerned by revelations it would introduce ads to Messenger. Although it declined to comment on the document, Facebook said it didn't want Messenger to become spammy.
"Our aim with Messenger is to create a high-quality, engaging experience for 800 million people around the world, and that includes ensuring people do not experience unwanted messages of any type," Facebook told TechCrunch.
The document also confirms Facebook the existence of its new short URL, which instantly opens a chat thread with a business. Canadian carrier Rogers is trialling the URL, offering a shortcut to a customer-service agent.
