ASP .Net MVC Routing: Url only with string ID

very simple question but I couldn't find an answer for this:

I have the default {controller}/{action}/{id} pattern in my global.asax.

I need also something will give me something like www.example.com/microsoft or www.example.com/apple while Microsoft and apple are id stored in database. Using the default pattern would be: www.example.com/brands/detail/microsoft

any idea how the pattern should be? i tried: {id} and set the controller and action to brands and detail it work to serve my need but ruins all others pattern.

thanks
