The Seven largest Open Source deals ever:

Here are the seven largest deals that we could find the numbers for:

1. Sun buys MySQL, $1 billion, 2008
Sun now has their hands on the world’s most widely used open source database.

2. Red Hat buys Cygnus Solutions, $675 million, 1999
Red Hat started the open source acquisition race early when they bought Cygnus Solutions, providers of open source software support.

3. Citrix buys XenSource, $500 million, 2007
Considering how hot virtualization is right now, we can see why Citrix bought XenSource, the company behind the Xen virtualization software.

4. Yahoo buys Zimbra, $350 million, 2007
Yahoo already have their own email services, and with Zimbra they got an integrated email, messaging and collaboration software.

5. Red Hat buys JBoss, $350 million, 2006
Red Hat strengthened their SOA offerings by buying the JBoss Java application server.

6. Novell buys SUSE, $210 million, 2003
Novell got their own Linux distribution by buying SUSE..

7. Nokia buys Trolltech, $153 million, 2008
Trolltech is the company behind the Qt GUI framework which is used by the popular Linux desktop environment KDE.

From this we can draw two different view points.
One side you can say how much impact Open Souce companies have created in the market by providing tough competition. On the other end, We can see the dominance of Big giants taking on such companies for their own market growth.

This trend can affect the Open Source community drastically in future. Nokia might change the licensing schemes for future Qt framework versions and Sun may also make future mysql release propritory. I hope the companies will not do such "evil" act.
