For 6 years, the Hangouts messenger has been installed about one billion times, but the times of its popularity are far in the past. First, Google brought to the market a new messenger Allo, leaving Hangouts only for corporate users. Now, according to rumors, the application will be completely removed.
By 2020, Google will stop working with Hangouts, or rather the application will be available only to business customers, and mere mortals will not be able to communicate in the application. At the moment there is no information about whether a new messenger will appear to replace Hangouts. As for Allo, users download it very inactively and at the moment the application is almost not popular.
In just a few years, Google abandoned 44 of its services, including the social network Google+.
