ruphus13 writes: As the pure-play Open Source companies continue to dwindle, Red Hat has thrived through the recession. Its support revenues have grown 20+%, and account for 75+% of its revenues. From the article, "Instead of the traditional strategy of selling expensive proprietary software licenses, as practiced by the Microsofts and Oracles of the world, Red Hat gets the vast majority of its revenues from selling support contracts. In the third quarter of last year, support subscriptions accounted for $164 million of its $194 million in revenue, up 21 percent year-over-year. All 25 of the company’s largest support subscribers renewed subscriptions, even despite a higher price tag."
