Register for the event here: http://www.cbofevents.com/ The Chicago Business Opportunity Fair (CBOF) is the longest running multi-day conference and trade fair focused on economic empowerment of minority business enterprises. Originally called the Business Opportunity Day in 1967, the success of the interactions between corporations and minority-owned businesses evolved with dramatic fashion.  The Business Opportunity Day was eventually organized by the Chicago Regional Purchasing Council, which ultimately blossomed into the National Minority Supplier Development Council in 1972.
