2016 - Google and Slack team up against Microsoft and Facebook


Recently Microsoft and Facebook launched their clones of popular collaboration service Slack (Teams and Workplace respectively). Of course for Slack it's a tough competition, so they found a partner in face of Google. The companies signed the strategic partner agreement and soon will tightly integrate their product. In particular, Slack will become available as an app in G Suite (formerly Google Apps), so admins will be able to turn it on/off for their users. And inside Slack you'll be able to preview documents via Google Docs editors, and sync access rights for files attached from Google Drive. Besides, Slack will get integration with the new service Google Team Drives (it's the recently launched team-focused version of Google Drive).

2016 - Microsoft introduced Teams - the main Slack competitor



In the beginning of the year Microsoft wanted to acquire super-popular group chat software Slack, but then decided to build the same own service from the scratch. And here it is - Microsoft Teams, and it looks very similar to Slack. You can create rooms for projects or departments, communicate from desktop or mobile devices and share files and other content. Like Slack, it features bots for notification and auto-replies. The main advantages of Teams (according to Microsoft) are its security and tight integration with other Microsoft applications, like Skype, Word, SharePoint, Planner and OneNote. Teams will be available for free in business subscription plans of Office 365. So Microsoft hopes that it will become the last straw for those companies that still don't use Office 365. Teams is now in preview mode and will be generally available in early 2017.
