RESTful Routes

I have purchased the peepcode tutorial on RESTful and I have to say it
is brilliant, one thing it does not answer is this question though.

I have been experimenting with rails on nothing serious and managed to
setup an application for which the routes did which for example did,

www.myapplication.com/company_name

therefore www.myapplication.com/google would pull up googles profile
from the database

I have looked at RESTful and that suggests www.myapplication.com/companies/company_name
would be the RESTful way to do it, does that mean using RESTful style
routes I cannot achieve the configuration "www.myapplication.com/
company_name"?

Or am I just a rails n00b whos missed the point of RESTful?

Thanks for any help anyone can give me!
