I’ve been waiting for a site like this since the early 80s when I learned that there were many more monopolies out there then I know about. This group makes me very happy.

KnowMore says:

We are a grassroots, web-based community dedicated to chronicling and resisting corporate attacks on democracy, worker’s and human rights, fair trade, business ethics and the environment. Our shared goal of a more informed and conscious consumer is being accomplished via this website: a vast database of easily searchable corporate and political info designed to aid responsible citizens, progressive thinkers and activists.

We are not affiliated with any political party, candidate, or PAC in any way. Our primary objective is to provide an independent, objective source of information to our readers about some of the most crucial, contested topics of our time.
