We found 673 companies on the donor rolls of our list of organizations – which was drawn heavily, though not entirely, from the Open Source Initiative’s list of affiliates.
Google was the biggest supporter of open-source organizations by our count, appearing on the sponsor lists of eight of the 36 groups we analyzed. Four companies – Canonical, SUSE, HP and VMware – supported five groups each, and seven others supported four. (Nokia, Oracle, Cisco, IBM, Dell, Intel and NEC.) For its part, Red Hat supports three groups – the Linux Foundation, Creative Commons and the Open Virtualization Alliance.
