Microsoft Office has been through a lot of changes since its original release in 1990. One notable milestone was the introduction of the Ribbon interface in Office 2007, but perhaps the most significant moment of evolution came in 2010, with the launch of docs.com – a collaboration with Facebook that allowed users to share documents with friends, discover documents that their friends had uploaded and even edit them collaboratively. It was shortly followed by the full Office Live Workspace service, alongside simple web-based versions of Word, Excel and PowerPoint.
Those early online services may not have had a huge immediate impact, but they laid the groundwork for Office 365, which came along in 2013 offering extensive cloud-based sharing and collaboration features.
