In September, 2016 Google rebranded Google Apps [for Work, for Education] to G Suite. In October, 2020 Google rebranded G Suite to Google Workspace.
In our opinion, Google Workspace is a much stronger brand name than G Suite. “Google” is better than “G.” “Workspace” is better than “Suite”, especially in today’s world.
What we observed in Google Trends about the first rebranding is that it took years for G Suite to leapfrog Google Apps as a search term.
