Google promises a new communication revolution with the launch of Google Wave, which is an online tool for real-time communication and collaboration. A wave can be both a conversation and a document where people can discuss and work together using richly formatted text, photos, videos, maps, and more (watch video demo below).

Google Wave was launched today (September 30) but it will only available for a small group of 100,000 lucky new users. These tests users will include public users who signed up early to test, developers, and a select group of Google Apps users, plus each new user will have 8 invitations to send out to their family and friends (these secondary users will not be given any invitation).

You can sign for an invitation here but don’t expect to get one today. As for the official public launch, Google Wave should be available to everyone on first half of 2010.
