Check out the interactive browser release chart.

The chart illustrates the most significant releases of each browser, regardless of arbitrary major/minor/micro version number changes. For instance, minor version bumps such as Firefox 3.6 were as significant in the Firefox timeline as major bumps were in Chrome’s.

That’s what I would describe as “the hopes and dreams of a generation” (of Software Freedom lovers), and is the result of fantastic product definition, branding, genuine user excitement, years of incredible — and largely unsung — work of thousands of Debian developers (not to mention all the upstreams)… and a pretty substantial X factor.

Update: Whenever I talk about this chart in presentations, I always follow up with another chart which puts that incredible rising line in context: Ubuntu vs. Firefox. Interestingly, that chart is looking far less impressive today than it was last year. Which is great news… The rise and rise of Ubuntu is catching up to the star power of Firefox! Wow!
