Google Wave is "a personal communication and collaboration tool" announced by Google at the Google I/O conference on May 27,2009

The name was inspired by the Firefly television series in which a Wave is an electronic communication (often consisting of a video call or video message).

Initially released only to developers, a "preview release" of Google Wave was extended to nearly 1 million users beginning September 30, 2009, with the initial 100,000 users each allowed to invite up to twenty additional users.
Features

Keep a single copy of ideas, suggested itinerary, menu and RSVPs, rather than using many different tools.Use gadgets to add weather, maps and more to the event.

Collaboratively work in real time to draft content,
discuss and solicit feedback all in one place
rather than sending email attachments and creating
multiple copies that get out of sync.

Drag and drop photos from your desktop into a wave.
Share with others. Use the slideshow viewer.
Everyone on the wave can add their photos, too.
It is easy to make a group photo album in Google Wave.

Prepare a meeting agenda together,
share the burden of taking notes and record decisions
so you all leave on the same page.
Team members can follow the minutes in real time,
or review the history using Playback.
Share Ideas
Bring lots of people into a wave to brainstorm - live concurrent editing makes the quantity of ideas grow quickly! It is easy to add rich content like videos, images, URLs or even links to other waves. Discuss and then work together to distill down to the good ideas.
And even more...
