People will not need both Messenger and Instagram apps to communicate.
From Facebook Blog Post
Facebook owns both WhatsApp and Instagram. And Facebook has its own Messenger app which needs to be installed separately from the main Facebook App. Messenger included tech from WhatsApp. Now the company is moving toward merging services between them, specifically adding new messaging options to Instagram.
So what’s the difference between the three? Good question, we’re glad that you asked. Instagram is primarily an image sharing service. People, even non celebrities, can make money from it through sponsored posts as long as they have enough followers. It is also used for political messages. WhatsApp is just for messaging and making both audio and video calls, which can also be done using Messenger. The difference: with WhatsApp you need someone’s phone number to contact them and with Messenger the other person must be your Facebook friend.
But wait, if you can already message people on Instagram and even call them, what’s the big deal.
Facebook says that people use its apps to send 100 billion messages to their friends and family each day. This number must be up since the start of the Corona Virus shutdowns. So the company states that this is the reason that it is blending Messenger and Instagram “to bring some of the best Messenger features to Instagram – so you have access to the best messaging experience, no matter which app you use.”
So people will not need both Messenger and Instagram apps to communicate with people who have accounts on only one of them. Since not all Instagram users have Facebook and vice versa, allowing for communication between the two platforms will make it easier for people to communicate. And just by sheer coincidence it will also make the two Facebook services more popular to use for communicating with people and give the company more targets for its targeted advertisements.
People on Instagram can decide whether or not to update their app for this.
