All the way back in 2010, Google announced that Google Wave was on its last leg, and then last November it said the web-based computing platform and communications protocol would become read-only, but today the service has been officially killed.

Well, users still have the rest of the day to export any important data. After tonight, however, all users must wave goodbye.

The Official Google Wave Blog provided more details on this termination at the Help Center. Further information is also available at Google Support.
