How do you think the Demand and Supply patterns have changed in the United states since 2008 when the recession started?

Question

I think the recession of 2008 decreased the demand of many goods especially the "Normal" goods in the country as a result the prices of such goods were reduced. This led to a change in the equilibrium prices of such goods.
Please I need help with this, as I am not very familiar with the economical system of the nation
