Is there a webpage out there that lists all the d20 D&D companies?

[Tuzenbach]

Because if there is, I haven't found it. I'm talking about a page with a clickable icon for ALL the d20 D&D companies that have a webpage. And perhaps a brief description of which persons founded which companies and when. Underneath the icon the name of a noteworthy product the company produces can be listed. Is this too much to ask for?

It's not exactly what you are talking about, but check EN World's Reviews. It has a lot of D20 publishers, with their websites and products.

EDIT: Scroll down on the left hand side until you see the "Full Publisher List" link.
