2018 - Google's Slack competitor Hangouts Chat is now generally available


After months of testing, Google is opening its business messaging platform, Hangouts Chat, to everyone. The Slack-like service for team communication is now open to all of the company's business customers who use its G Suite services. Google is a relatively late entrant to the business-messaging software game. At this point, Slack and Microsoft, with its Teams app, both have significant head-starts. But there are a few areas where Google is hoping to differentiate itself from the competition. By being directly integrated into all the Google services businesses are already using, like Drive and and Google Calendar, Hangouts Chat can streamline tasks like file sharing and scheduling meetings. For example, Google's meeting-scheduling bot will be able to automatically schedule team meetings based on each person's calendar.

2017 - Google splits Hangouts into Chat and Meet. Slack should better react


Google is making massive changes to Hangouts to make it more business-friendly. The service will be splitted into two separate apps: Hangouts Meet, a videoconferencing app, and Hangouts Chat, a Slack-like messaging app designed for teams.  Meet is a revamped version of Hangouts' video calling features, with a few new additions designed for businesses. Like the old Hangouts, it supports video calls of up to 30 people and participants can join via their desktop or the mobile app. While anyone with a Gmail account can use Meet, Hangouts Chat is just for Google's enterprise users. Essentially a full-on Slack competitor, the service allows teams within organizations to chat and supports a variety of third-party integrations, including bots and other productivity apps. Google also created its own bot for the app, which will schedule meetings on your behalf.
