When it comes to forays into social media, Google is remembered more for Google+ than the much older Google Wave. Announced ten years ago this week, Google Wave was a monster of messaging, collaboration, and extendibility.
It had file sharing. It had real-time conversation. It was built to add applications and extensions. Google Wave even had its own vocabulary Just one screenshot gives you the impression of a weird tech turducken, with email and messaging and social media features crammed together onto a single busy screen.
The complexity might have been too much. Less than 18 months after announcing Google Wave, Google decided to discontinue it due to low user adoption, announcing a slow shutdown that completed in 2012.
Google Wave was open source, so when Google announced its shutdown it passed on the technology to the Apache Software Foundation's incubator program, where it became known as Apache Wave. Apache Wave lasted far longer than Google Wave, but was finally retired in early 2018.
