The old Hangouts service was just a relic waiting to be killed, and now the multicoloured grim reaper has drawn its scythe. Google's new messaging effort Chat won't take off before 2019, and that is probably the main reason why the consumer version of Hangouts is retired in 2020 and not in 2019.
Google has a history of shelving services that arent as popular as they once were.
The platform has seen several major changes since its inception but Google has put its development on the backburner, instead focusing on its more recent services: Google Allo and Duo.
Hangouts for Enterprise customers was split into Hangouts Chat and Hangouts Meet back then. The idea so far, from whatever we know at the moment, is to create with the RCS messaging app something that is similar to Apple's iMessage that is only available to iPhone users. However, instead of working on improving Google Talk, the tech company simply chose to kill it and launched Hangouts.
Stop us if you've heard this one before: there's a report that Google is considering either launching or shutting down a messaging app. In 2016, Hangouts was demoted, if not immediately killed, by Google as it launched a new messaging app called Allo for text and multimedia messages and Duo for video calls.
