I knew that Google represented a majority of Mozilla's revenue, but 85 percent? That's what Mozilla recently reported, as pointed out by The Register. The good news is that it's in Google's interest to continue feeding a competitor to Microsoft's Internet Explorer. The bad news is that it has to do so much feeding.
In 2006, Mozilla pulled in revenues of $66,840,850. That's up 26 per cent from 2005, and as Baker says, most of it can be traced back to Mountain View. "As in 2005 the vast majority of this revenue is associated with the search functionality in Mozilla Firefox, and the majority of that is from Google." A customized version of Google.com pops up when you launch Firefox, and there's a Google search box tucked into the browser's top right-hand corner.
I use that search box all the time. But I also use Adblock Plus, so I never see a Google ad. Ever. Should Google worry? Should Mozilla?
As noted before, Firefox. Treating it as a public asset is nice, but public goods have a tendency to have lots of users who use without replenishing. Mozilla needs to figure out a way to make money that doesn't entirely depend on Google's beneficence. It's fantastic that Mozilla made $66 million last year.
It would be better if it weren't reliant on one customer.
