The Linux operating system is the recipient of 75% of all vendor investment in open source software, according to a new report from the Harvard Business School, which also indicates that vendor support for open source is primarily motivated by boosting their proprietary offerings.
The preliminary draft report suggests that $2bn was invested by vendors in open source software between 1995 and 2005, with $1.5bn plowed into Linux, $317m into the Firefox browser, $76m into the OpenOffice.org productivity suite and $48m into the MySQL database.
The only other projects to receive significant vendor backing, according to the study, were the PHP scripting language with $24m, the Tcl scripting language with $15m, and the JBoss middleware stack with $10m.
Although numerous investments since 2005 would change the picture, and the Eclipse tools project appears to be a notable omission.
